Bioinspired strengthening and toughening of carbon nanotube@polyaniline/graphene film using electroactive biomass as glue for flexible supercapacitors with high rate performance and volumetric capacitance, and low-temperature tolerance

Electroactive biomass tannin was used to glue rGO and CNT@PANI which endows the CNT@PANI/rGO/TA film with high strength, toughness, and low-temperature energy storage performance.
