摘要：

A novel three-dimensional graphene/polyaniline (3DGP) composite was achieved by a hydrothermal method from in situ polymerization of a polyaniline/graphene oxide composite and GO suspension. This 3DGP composite possesses a 3D porous network structure and large specific capacity of 648 F g(-1) at a current density of 0.5 A g(-1). In particular, the capability can reach 356 F g(-1) even at 20.0 A g(-1), 537 F g(-1) at 1.0 A g(-1) can also be achieved after 1000 cycles. Therefore, the 3DGP composite is a suitable and promising electrode material for supercapacitors.
