Preparation of StarShaped PolyacrylonitrileGraphene Sheets Composite via π-π Interactions

Triphenylene derivative containing six hydroxyl groups was synthesized. Then, starshaped 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 starshaped polyacrylonitrile FT-IR, 1H-NMR, GPC and SEM were used to investigate the chemical structure, morphology of polymercoated graphene sheets. Results show that the starshaped polyacrylonitrile is successfully adsorbed on graphene sheets.
