摘要：Graphene films are essentially important to enable the excellent in-plane properties of graphene being utilized to the maximum extent at macroscopic scale, which can be directly grown by chemical vapour deposition (CVD) or assembled from graphene/graphene oxide (GO) nanosheets. In this talk, I will first introduce grain size and number of layers control, doping and clean transfer of CVD-grown graphene films and demonstrate their applications for flexible OLEDs. Then, I will introduce the synthesis of GO-based films with controlled alignment and compaction, and demonstrate their applications for high-performance nanofiltration membranes, super-strong and highly conductive papers, electromagnetic interference shielding membranes, and flexible supercapacitors with record volumetric energy density.
