Facile synthesis and characterization of three-dimensional graphene/polyaniline composites with enhanced electrochemical properties

Honeycomb graphene–polyaniline nanocomposites as novel electrode materials for high-performance supercapacitors

“…The specific capacitance of the hybrid electrode material in the three-electrode system was as high as 565 F g −1 at a current density of 0.1 A g −1 . Li and co-workers 34 reported the production of three-dimensional 3D graphene/PANI aerogel composites (GPA) by in situ polymerization of aniline within graphene hydrogels by ultrasonic treatment, leading to the introduction of polyaniline (PANI), where polyaniline could be dispersed as twisted nanorods in the interconnected porous 3D graphene. The specific capacitance of the material was 618 F g −1 at a current density of 1 A g −1 .…”
