Polymerization Method

Polyaniline/Graphene composite (PANIGNS) was synthesized via in situ polymerization method. XRD and SEM results indicated that the polyaniline could uniformly adsorb on the graphene surface and prevent the agglomeration of the graphene sheets. The composite exhibits excellent electrochemical performance. A specific capacitance of 688F/g at current density of 1A/g was achieved in 1M KOH solution. The capacitance retention of 77.3% was acquired after 1000cycles at current density of 10A/g.

Supercapacitor Electrode Materials

The amino-functionalized graphene/polyaniline nanocomposites (AGNS/PANI) were fabricated through in-situ chemical oxidative polymerization of aniline in the presence of amino-functionalized graphene sheets (AGNS). FTIR, UV-vis spectroscopy analyses revealed that aminophenyl groups covalently bound to the basal plane of graphene via a diazonium addition, and the polyaniline chains grafted to graphene sheets. The FE-SEM images show that PANI nanorods aligned vertically on the surface of graphene. The AGNS/PANI nanocomposite exhibits excellent electrochemical performance for supercapacitor electrode materials.
