Graphene fever has passed over a decade since its first isolation in 2004 and a great number of applications have been demonstrated in laboratories and even at industrial scale. However, a huge gap still exists between the ideality and the reality. The ideal graphene material is composed of single crystalline hexagonal honeycomb lattice of sp2 hybridized carbon atoms while the experimentally available graphene is a polycrystalline film with lots of structural defects and unexpected noncarbon impurities. As a result, the observed properties of graphene are far from theoretical predictions. The key to bury this gap is the controlled synthesis towards perfect graphene. It is no doubt that the synthesis will determine the future of graphene material. On the other hand, it is also a crucial challenge to find out the killer applications of graphene, which would create a realistic graphene industry.

We are targeting to build the footstone of future graphene industry from the material synthesis point of view. We have made great efforts to grow high-quality graphene film on copper foil towards industrial level mass production. Currently we are able to grow cm sized single crystalline graphene film with high growth rates. For practical applications, we have succeeded in growing high quality graphene films on traditional glasses. The graphene endowed glass with extremely high thermal and electrical conductivities, leading to a new type of super graphene glasses. In a similar way, the graphene film has been deposited onto optical fibers under a high-temperature growth process, creating a graphene-decorated optical fiber. Various promising applications are demonstrated with these super graphene glasses and graphene-covered optical fibers.

Prof. Zhongfan Liu graduated from Changchun Institute of Technology in 1983 and received his PhD from University of Tokyo in 1990. After a postdoctoral experience at Institute for Molecular Science, Japan, he became an associate professor (1993), full professor (1993) and Cheung Kong Chair professor (1999) of Peking University. He was elected as the member of Chinese Academy of Sciences in 2011 and as one of the six outstanding scientists in Ten-Thousand-Talents Program in 2013.

 

Prof. Lius research interest focusses on low dimensional carbon materials and novel 2D atomic crystals targeting nanoelectronic and energy conversion devices together with the exploration of fundamental phenomena in nanoscale systems. He has published over 480 peer reviewed articles and 28 Chinese patents. The academic awards he received include, Outstanding Young Scientist Award of Hong Kong Qiushi Foundation (1997), MOE Science and technology Award (1st class, 2007), National Natural Science Award (2nd class, 2008), Chinese Chemical Society-AkzoNobel Chemical Science Award (2012), Baogang Outstanding Teacher Award (2012), and Founder Special Prize (2016).

 

He is now the director of Beijing Graphene Institute (BGI). He also serves as advisory/editorial board member of Adv. Mater., Small, Nano Res, ChemNanoMat, Natural Science Review, Graphene Technology and NPG Asia Mater, and Editor-in-Chief of ACTA PHYSICO-CHIMICA SINICA and the associate editor of Chinese Science Bullentin. Prof. Liu is the Fellow of the Institute of Physics (UK, 2004), the Fellow of Royal Society of Chemistry (UK, 2014) and the Fellow of TWAS (The World Academy of Sciences for the advancement of science in developing countries, 2015).
