Abstract:
Triphenylene derivative containing six hydroxyl groups was synthesized. Then, starshaped polyacrylonitrile(SPAN) was obtained by the redox system of tetravalent cerium salt and hydroxyl groups. Finally, homogeneous black dispersion solution was obtained via the chemical reduction of graphite oxide in the N,N-dimethylformamide solution of starshaped polyacrylonitrile FT-IR, 1H-NMR, GPC and SEM were used to investigate the chemical structure, morphology of polymercoated graphene sheets. Results show that the starshaped polyacrylonitrile is successfully adsorbed on graphene sheets.
