Harbin researchers 3D print the un-printable with graphene oxide injected ink

View Larger Image


Researchers at the Harbin Institute of Technology and Ministry of Education in China have released a paper demonstrating the use of graphene oxide in a 3D printable ink.

The material developed by the team in China exhibits a tensile strength putting it in the same performance range as high-strength concrete, and a level of electrical conductivity among the highest conductive ceramic nanocomposites.

Finding the flow

At its base, the 3D printable ink in this study is a geopolymer – a material first defined in the 1950s with heat resistant and insulating properties, and an ability to encapsulate waste material in its structure. Examples of geopolymers include high temperature ceramics, and concrete made from recycled materials, such as the géobéton created by Russian construction company Renca.

As a raw material, the geopolymer alone does not have the rheological properties to flow through a nozzle for 3D printing. And so, in order to change its rheology (flowability), researchers investigate the use of graphene oxide as an additive.

Materials in the mix

The base geopolymer is made from a mixture of alkaline-source particles, found in soil or clay, and aluminosilicates particles, which is a mineral consisting of aluminium, silicon, and oxygen. During stirring, graphene oxide (GO) particles are injected into the mixture to create four samples of the material with different GO to geopolymer ratios.

What happens in the molecular structure of the geopolymer is that the GO particles act as a kind of lubricant in between the alkaline-source particles and aluminosilicates. The study assumes that interaction between the particles creates a thick layer of water film between them and, as such, GO/Geopolymer inks with higher GO concentration are more fluid than the others.

Printing the un-printable

3D printing this ink is performed using a modified commercially available UP Plus2 3D printer. After direct writing the ink into a design, the structures are cured in a controlled chamber for 5 days. They are then sintered at 1000? to turn the graphene oxide particles of the mixture into graphene, giving extra strength and conductive properties.

As a conclusion, authors state that

The unique properties of GO as we show in this study will further expand the range of applications where GO can be used. In particular, our strategy makes it possible to explore the employment of GO as rheology property modifier by encapsulation, and enable 3D printing materials that was un-printable previously, and thus offer opportunity to create new 3D printing materials

In the form of carbon nanotubes, graphene is gaining widespread popularity in the 3D printing industry. Award winning 3D printer company Markforged is a leader in the field of carbon fiber 3D printers, and fiber-reinforced materials have become a hot topic for applications in automotive and aerospace components.

Researchers at MIT have also taken a theoretical approach to 3D composition of graphene that, by nature, exists as a single-atom sheet.

3D printing strong and conductive geo-polymer nanocomposite structures modified by graphene oxide discussed in this article is published online in Carbon journal, Volume 117, June 2017. It is co-authored by Jing Zhong, Guo-Xiang Zhou, Pei-Gang He, Zhi-Hua Yang and De-Chang Jia.

Zenyatta Ventures forms ZEN-Tech Materials

2017-07-25 08:43 ET - News Release

Mr. Aubrey Eveleigh reports

ZENYATTA ANNOUNCES THE FORMATION OF A WHOLLY OWNED SUBSIDIARY, ZEN-TECH MATERIALS LTD., TO DEVELOP & COMMERCIALIZE GRAPHENE RELATED OPPORTUNITIES

Zenyatta Ventures Ltd. has formed a wholly owned subsidiary called ZEN-tech Materials Ltd. with a registration in England and Wales. ZEN-tech will focus on the development and commercialization activities of graphene applications and the allocation of any associated intellectual property (IP) and worldwide licensing. The formation of ZEN-tech is a strategic move that will provide a vehicle to capture value and advance graphene application development separate from the mineral development company. Zenyatta will continue to focus on advancing the Albany graphite deposit toward production and will supply highly crystalline, purified graphite to ZEN-tech, academics and end-users.

"It has become apparent in the last 12 months that Zenyatta has created additional value from our global collaboration and development related to various graphene initiatives. It makes strategic sense to create a subsidiary to hold the various opportunities and handle these initiatives with our partners," stated Aubrey Eveleigh, president and chief executive officer of Zenyatta. "ZEN-tech has the advantage of developing proprietary graphene-based technology with a consistent supply of high-quality raw material from Zenyatta's wholly owned Albany graphite deposit. We have demonstrated that Zenyatta's graphite converts (exfoliates) easily via sonication to graphene, including mono-layer to tri-layer, has excellent dispersion properties and is highly suitable for many graphene and graphene-oxide applications."

Graphene has shown to enhance the properties of many existing products since its discovery in 2004. The technology pipeline for ZEN-tech includes graphene applications for concrete composites, rubber composites, sensors, filtration, emulsions and silicon-graphene batteries. The formation of a subsidiary will help facilitate and focus the integration of Zenyatta graphene into the next generation of commercial technologies, providing various industries with advanced materials that have improved performance.

ZEN-tech, a private incorporated company, will have access to the high-purity graphite from Zenyatta Ventures for graphene and graphene-related opportunities. There is a high level of interest, especially in Europe, from sophisticated technology or cleantech entities, particularly related to a need for access to a unique raw material graphite source that converts to high-quality graphene for various applications.

Zenyatta and Alliance Rubber Initiate Collaboration with University of Sussex on Graphene Enhanced Rubber Products

2017-07-27 09:41 ET - News Release

Mr. Aubrey Eveleigh reports

Zenyatta Ventures Ltd. has begun a collaboration program with Alliance Rubber Company and the University of Sussex, United Kingdom, to develop enhanced rubber products using graphene converted from the company's high-purity Albany graphite.

Alliance, an American company founded in 1923, is based in Hot Springs, Ark., that manufactures 2,200 products and markets them in 55 countries. It is financing research at Sussex under the guidance of Dr. Alan Dalton, professor of experimental physics, to develop enhanced new rubber products using graphene produced from Zenyatta graphite. The program is focused on rubber sensor products that will hold credit and debit cards to prevent hacking of information stored on the chip. The global radio frequency identification (RFID) chip market is growing rapidly from $5.6-billion (U.S.) in 2010 to a projected market value of $21.9-billion (U.S.) in 2020*. This market includes software/services, labels, fobs, tags, readers and all other similar types.

The Alliance program will also focus on a rubber sensor product attached to food produce that changes colour when the produce item reaches a set temperature or after a certain amount of time passes since harvest. This product can also act as a bar code on produce in grocery stores.

Jason Risner, director of business strategy at Alliance, stated: "Alliance has a long history of innovation and it is vital for us to play an active role in leading edge rubber technology that uses a disruptive nanomaterial like graphene. It is also critical that we partner with scientific leaders like Dr. Alan Dalton at Sussex and a company like Zenyatta with a special raw material graphite source located in North America."

Graphene can enhance the mechanical, thermal and electrical properties of a vast range of composite materials. It can be added to rubber to make it lighter, stronger and conductive for improving its performance in a large variety of industries.

Separately from the above Alliance project, Zenyatta will also be working with a team of scientists at Sussex under the direction of Dr. Dalton using graphene produced from Zenyatta graphite on other projects such as:

-Motion sensors: Create a flexible (rubber-graphene) sensor that can detect motions as subtle as those associated with breathing and pulse for health care monitors and sportswear use.
-Emulsions: Where the control of electrical and thermal properties is critical for performance. Examples of such applications include inkjet printing, thin wires, stress sensors, thermal management liquids and fluid conductors.
-Energy storage devices -- The goal is to develop supercapacitor devices based on a self-assembly of nanomaterials to produce electrode structures and a better battery using graphene.
-Automotive industry: to develop more sensitive airbags and vehicle batteries made with stacked graphene for faster charging and more energy.
Aubrey Eveleigh, president and chief executive officer of Zenyatta, commented: "We are very pleased to have a collaborative research program with an end-user like Alliance and the great team of scientists at Sussex on exciting new and innovative products. Technology companies around the world are making significant investments which are accelerating the pace of graphene development. We are delighted to play a part in the advancement of this new innovative material by providing a high-quality and consistent graphite material for conversion to graphene."

Tokyo Tech Identifies Key Reasons for the Ease & High-yield Conversion of Zenyatta's Albany Graphite to Graphene

2017-10-19 09:02 ET - News Release

Mr. Aubrey Eveleigh reports

Testing results from the Tokyo Institute of Technology in Japan have identified key reasons for the ease and high-yield conversion of Zenyatta Ventures Ltd.'s Albany graphite to graphene.

Research at Tokyo Technology provides exciting feedback on Zenyatta graphene

One of the greatest challenges for commercializing graphene in various applications, since its discovery at the University of Manchester, is how to produce high-quality material, on a large scale at low cost, in a consistent manner.

Dr. Yoshihiko Arao, assistant professor in the department of chemical engineering at Tokyo Tech, stated: "Zenyatta's high-purity graphite material was tested by our scientific team on mechanical conversion to graphene and discovered it converted much easier and with higher yields of graphene than our reference material. We have tested many types of natural graphite but found Zenyatta's graphite material to have better exfoliation performance and produce better graphene particles than the reference material. We believe that this is an extraordinary, unique material and we would like to carry out further collaborative work with Zenyatta on graphene applications."

Research by Dr. Arao and professor Dr. Masatoshi Kubouchi at Tokyo Tech has shown the following significant test results:

D-spacing measurements of Zenyatta carbon material is relatively larger compared with three other commercially available high-purity graphite samples. D-spacing is unique to all crystals and described as the distance between two (graphene) atomic layers or interlayer spacing. The Albany graphite also exhibited some turbostratic structure or natural irregular stacking.
Importantly, these factors have contributed to the ease of conversion and greater yield of high-quality graphene from Albany graphite. This can be attributed to the unusual geologic mode of formation (igneous hydrothermal process) which accounts for the superior purity, crystallinity and overall quality of the graphite found in this unique deposit.
Graphene exfoliated from Albany graphite showed the highest aspect ratio with an average thickness of 1.43 nanometres or one to four graphene layers. Also, the optical absorbance of the Zenyatta graphene dispersion was two to 10 times better than the other three tested reference samples which demonstrate concentrated graphene dispersion can be obtained.
This further confirms the reason for success on graphene development initiatives, especially in composites, from other collaborators in the United Kingdom, Canada, United States and Israel. Tokyo Tech has established that Zenyatta's graphite converts (exfoliates) easily to graphene, producing mono-layer to tri-layer material, has excellent dispersion properties, and is highly suitable for many graphene and graphene-oxide applications.
Aubrey Eveleigh, president and chief executive officer for Zenyatta, stated: "The obstacle to widespread use of graphene since discovery is the high manufacturing cost. A lower-cost and disruptive approach is to use high-purity natural graphite, like Albany material, as the starting point to get easier and higher yields of graphene in an environmentally friendly manner. We are eager to start another phase of testing at a world-class facility like Tokyo Tech using our high-purity graphite material for various innovative graphene applications."

Zenyatta Ventures continues to develop its large and unique Albany graphite deposit in Ontario, Canada. The company's highly crystalline graphite deposit is situated 30 kilometres north of the Trans-Canada Highway, power line and natural gas pipeline near the communities of Constance Lake First Nation and Hearst. A rail line is located 30 km away with an all-weather road approximately 10 km from the graphite deposit. The world trend is to develop products for technological applications that need extraordinary performance using ultrahigh-purity graphite powder and graphene at an affordable cost.

Aubrey Eveleigh, PGeo, president and CEO for Zenyatta, is a qualified person for the purposes of National Instrument 43-101 and has reviewed, prepared and supervised the preparation of the technical information in this news release.

Moat? Does anybody have one? I am looking into this material as something to invest in. I cannot tell who if anyone has significant IP for processing into useable material efficiently, or applying graphine in a novel way. Is this just a bunch of miners and chemical companies that will leverage what is essentially a new material in the public domain. I can't find the edge. Is there one? Love to hear thoughts on where the gatekeepers/tolltakers are.
