electrically and electrochemically active composite based on polyester/reduced graphene oxide/polypyrrole with remarkable washing durability

The present work explores a facile route toprepare a durable conductive fabric by using reducedgraphene oxide and polypyrrole. prior to coating of activematerials, polyester surface experienced a modificationwhich resulted in high uptake of materials. then, dipcoatingapproach was used to deposit graphene oxideon the modified polyester. after reduction of grapheneoxide, polypyrrole particles grew on the fabric surfacethrough an in situ polymerization method. sem, xrd,ftir, and tga were employed to investigate themorphology and chemical structure of the samples. a highelectrical conductivity of 0.98 s.cm^-1 was obtained whicharises from establishing the numerous conduction routesin the structure. a mere decrease in conductivity after 20laundry cycles confirms the excellent washing durability ofthe conductive fabric. moreover, a high specific capacitanceof 8.3 f.g^-1 was recorded for this fabric by cyclic voltammetryin a three-electrode measurement system.
