Talking graphene standardization with NPL's Andrew J. Pollard

Dr. Andrew J. Pollard (NPL)In November 2017, after years of work, the International Organization for Standardization (ISO) released its first graphene standard, the ISO/TS 80004-13:2017. The effort was led by the UK's National Physical Laboratory (NPL).

We recently discussed this interesting and important development with the NPL's Dr. Andrew J. Pollard. Dr. Andrew leads the NPL Surface and Nanoanalysis Group's research into the structural and chemical characterization of graphene and related 2D materials, and he is also a member of the ISO working group 'Measurement and Characterization' within the 'Nanotechnologies' Technical Committee (TC229), and a UK nominated expert for the international graphene standards.

Hello Andy, and thank you for this interview. We know that NPL pioneered the effort in the new ISO standard, can you tell us why do you believe such standards are of vital importance?

As a new material that has spawned an emerging industry, graphene has the potential to improve many of the products we all use every day. However, for industry around the world to be able to develop innovative products with this two-dimensional material, they need to know what the properties actually are of the materials they are using.

XFNano’s CEO discusses the company’s business and technology

Mr. Xu Jiang, president and general manager of China’s XFNano, was kind enough to answer a few questions we had for him regarding XFNano’s graphene materials, technology and business. Mr. Jiang founded XFNano in 2009, and he holds a master’s degree from Nanjing University of Posts and Telecommunications.

Q: Hello Mr. Jiang, thank you for your time. Can you update us on your graphene production process and facilities?

In 2016, XFNANO put its new production line into operation, which yields an annual production capacity of 50 tons of high-quality graphene powder and 1,000 tons of graphene dispersion. We believe this can meet our customers’ demands for large quantities.

CealTech's marketing and sales manager explains the company's technology and business

Michel Eid (CealTeach)Norway-based CealTech was established in 2012 to commercialize a patented 3D graphene production method. The company recently received its first prototype proprietary industrial-scale Plasma-Enhanced Chemical Vapor Deposition (PE-CVD) graphene production reactor.

We discussed CealTech's technology and business with the company's marketing and sales manager, Michel Eid. Michael holds a Ph.D. in Solid Mechanics from the Ecole Polytechnique in France, and held various roles in engineeing, manufacturing, sustaining, sales, marketing and business development. Michel joined CealTech in January 2017.

Q: Hello Michael. CealTech is commercializing a patented 3D graphene production method. Can you give us some details on the process and the material you are producing?

Our production process is based on David Boyd’s technique as per Nature communications (DOI: 10.1038/ncomms7620), ‘Single-step deposition of high-mobility graphene at reduced temperatures’. In summary, the substrate is directly exposed to a low-pressure, microwave hydrogen plasma containing small amounts of methane as carbon source. During this process, vertical grown graphene flakes nucleate and arrange perpendicularly to the surface of the substrate forming a so-called 3D network of non-agglomerated graphene flakes.

Talga Resources' CEO: 2017 will be a turning point for graphene commercialization

Mark Thompson, Talga Australia-based technology minerals company, Talga Resources, is actively developing graphene materials and graphene-based applications across many areas, including coatings, batteries, construction materials, composites and more.

Mark Thompson, Talga's managing director, was kind enough to update us on Talga's graphene program and answer a few questions we had.

Q: Thank you for this interview, Mark. Can you quickly update us on your graphite mine operation in Sweden?

Talga has over 20 years of graphite mining potential outlined in economic studies to date and currently extracts intermittently what it needs for scale up and testing purposes. Talga mined approximately 5,000 tonnes of graphite ore during 2015-16 trial mining operations. Further extraction is not required for now but permitting for the future larger scale operations is underway.

Updates from Prof. James Tour's graphene lab at Rice University

Prof. James Tour's research lab in Rice University is one of the leading graphene research groups in the world, with several key technologies first discovered and developed there. Professor Tour is involved with several application areas - from de-icing coating to energy storage and quantum dots production. Prof. Tour was kind enough to share his time and update us on the latest research and commercialization efforts at his lab.

The Tour group is now commercializing two of its key technologies. First up is the laser-induced graphene (or LiG), which was reported first in 2014. This is a process in which graphene is formed on a flexible polyimide film using a room-temperature laser-based process. It is possible to pattern this graphene to create devices and as it is formed on a flexible film this easily enables flexible electronics applications.
