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.

High-speed and on-silicon-chip graphene blackbody emitters

A research team from Japan has developed an integrated, high-speed and on-chip blackbody emitter based on graphene. The team reports that the device operated in NIR region including telecommunication wavelengths. A fast response time of ~ 100 ps, which is ~ 105 higher than the previous graphene emitters, has been experimentally demonstrated for single and few-layer graphene, the emission responses can be controlled by the graphene contact with the substrate depending on the number of graphene layers.

The team stated that graphene light emitters are greatly advantageous over conventional compound semiconductor emitters because they can be integrated on silicon chips due to simple fabrication processes of graphene emitters and direct coupling with silicon waveguide through an evanescent field. Because graphene can realize high-speed, small footprint and on-Si-chip light emitters, which are still challenges for compound semiconductors, the graphene-based light emitters can open new routes to highly integrated optoelectronics and silicon photonics.

EU project to develop graphene-based products for protection of artwork

An interesting project under the H2020 initiative is GRAPHENART - focused on examining graphene as an anti-fading agent for the protection of artworks. The project, funded at about €150,000, started at October 2017 and will go on until March 2019.

The reasoning behind the project is that fading, yellowing and discoloration are common degradation effects that result from exposure to UV and visible light and oxidizing agents, resulting in the irreversible alteration of the appearance of contemporary artworks. The GRAPHENART project aims to develop innovative, multi-functional graphene-based products (graphene ‘veils’ and inclusions) that provide UV shielding, de-acidification, oxygen and humidity barriers for the protection of old and modern paintings and artworks.

Graphenea launches a Chinese website to target the growing Chinese graphene market

Spain based graphene producer Graphenea has launched a new Chinese edition of its web site to specifically target the growing Chinese graphene market. China is becoming a leading adopter of graphene technologies, and Graphenea aims to supply its high-end materials for corporations in China.
