Chao Gao is a professor in Zhejiang University. He received his Ph. D. in 2001 on Polymer Chemistry and Physics in Shanghai Jiao Tong University (SJTU), M.Sc., and B.Sc. both on Chemical Engineering from Hunan University, in 1998 and 1995, respectively. Since 2001, he became a faculty member in SJTU, and associate professor in 2002. Since Nov. 2003, he worked with Prof. Sir Harry Kroto as a visiting scholar and post-doc research fellow in University of Sussex, UK, and then moved to Prof. Axel H. E. Müller’s group at Bayreuth University, Germany in July 2005 as an Alexander von Humboldt research fellow. In 2008, he joined Zhejiang University, and was promoted as full professor.
His research interests include hyperbranched polymers, chemistry of graphene and carbon nanotubes, controlled/living polymerization and click chemistry. He co-edited a book on hyperbranched polymers (published by John, Wiley & Sons) and published more than 100 papers with citation of more than 4500 times and H-index 33. His research of graphene fiber knot has been selected by Nature as “Images of the Year” in 2011. He was awarded or funded with National Science Fund for Distinguished Young Scholars (2013), the least dense solid Guinness World Records (2013), “Gold Kangaroo” World Innovation Award (2013), Academician of Asia-Pacific Academy of Materials (APAM) (2013), Zhejiang Youth Technology Award (2013), the Second Prize of National Natural Science Award (2009), the First Prize of Shanghai Science and Technology Award (2007), and Top 100 National Excellent Doctoral Dissertation of China (2005). He is the Regional Editor of Colloid and Polymer Science.

Abstract
Graphene fibers (GFs) are a novel kind of carbonaceous fiber assembled from graphene or graphene oxide (GO). Wet-spinning of GO liquid crystal dope followed by chemical reduction produces GFs continuously. By addition of polymer and inorganic nanoparticles to the spinning dope, continuous nacre-mimetic fibers are achieved, which are strong, flexible, electrically conductive, and chemical-resistant. GFs are used directly as electrodes to construct flexible yarn supercapacitors. Compared with the conventional carbon fibers, GFs possess advantages of, 1) rich raw material of graphite, 2) simple preparation process, 3) superior functionality such as thermal and electrical conductivities, 4) easy integration with other host components to fabricate tailor-made composite fibers, 5) structure flexibility and great potential in many applications.
