- 3D RGO-g-PANI composite was efficiently prepared by a facile hydrothermal method.
- The obtained specific capacitance was as high as 1600Â FÂ gâ1 at 12Â AÂ gâ1.
- The cycling stability was 91.3% capacitance retention after 3000 cycles.
Three-dimensional polyaniline grafted reduced graphene oxide (3D RGO-g-PANI) composite was prepared by an efficient two-step method. Firstly, graphene oxide sheets were grafted with PANI chains, forming graphene oxide grafted PANI composites. Secondly, RGO-g-PANI aerogels were obtained from GO-g-PANI composites by hydrothermal and drying processes. The 3D RGO-g-PANI aerogel composite was used as active materials to coat the glassy carbon electrodes for checking the electrochemical properties for supercapacitor application. The obtained specific capacitance was 1600Â FÂ gâ1 at a very high current density of 12Â AÂ gâ1 and an excellent cycle stability (91.3% capacitance retention after 3000 cycles), suggesting its potential application for a high performance supercapacitors.
