摘要: Abstract Three-dimension (3D) conductive network was successfully constructed by carbon nanotubes (CNTs) and graphene sheets (G) on the polyester fabric (PETC) using a “dipping-drying” process electrophoretic deposition method, which facilitates to greatly enhance electron transportation rate shorten electrolyte ion diffusion distance. The resultant composite provides promising substrate prepare textile-based electrodes for flexile supercapacitors. After further coating CNTs with polyaniline (PANI), polyaniline/carbon nanotubes/graphene/polyester (PANI/CNTs/G/PETC) textile electrode exhibited high electrochemical performances. showed maximum areal capacitance of 791 mF cm −2 at current density 1.5 mA cm . Compared some reported PANI fast decay in capacity, retentions over 76% even after 3000 charge-discharge cycles. Moreover, also stable performances under mechanical bending stretching conditions.
