The invention provides a kind of cotton-shaped polyaniline-coated graphene composite material and its preparation method and application, take single-layer graphene as skeleton, and cotton-shaped polyaniline is in the growth of graphene sheet layer two sides, and polyaniline is connected with covalent linkage with graphene film interlayer.This matrix material has good electroconductibility and high specific surface, as electrode materials, there is very high ratio capacitance, the stability of covalent linkage ensure that the cycle charge discharge elctrical stability that electrode is good, and the synergy of the two is that it is laid a good foundation in the application of electrode material for super capacitor. |
