Recently, the Ma Yanwei team of the Institute of Electrical Engineering of the Chinese Academy of Sciences has made significant progress in the preparation and dispersion of graphene. The relevant results were published in the Chemical Society of the British Chemical Society (Chem. Commun., 2009, 4527-4529). This paper first reported the use of p-phenylenediamine reduced graphite oxide nanosheets to successfully prepare graphene materials with high stability organic solvent dispersion, and obtained a highly conductive graphene film by electrophoretic deposition method, and its conductivity was 150S. /cm. The graphene prepared by the method has good dispersing performance, high yield, good electrical conductivity and low cost, and is expected to be applied to fields such as supercapacitors and composite functional materials.
Graphene is a new carbon structure structure discovered by scientists after fullerenes and carbon nanotubes. It is a single-layer plane formed by sp2 hybrid carbon atoms to form a hexagonal lattice honeycomb two-dimensional structure. graphite. Graphene has excellent electrical, thermal and mechanical properties, and has broad application prospects in the fields of supercapacitors, room temperature ballistic field effect transistors, ultrasensitive sensors, micromechanical resonators, composite functional materials and nonlinear optical materials.
