摘要:The present disclosure further provides an exemplary energy storage device fabricated from rectangular-tube polyaniline (PANI) that is chemically synthesized by a simple and convenient method. The rectangular-tube PANI, as an active material, is synthesized on a functionalized carbon cloth (FCC) as a substrate, and the obtained composite is immobilized on a stainless steel mesh as a current collector. The present disclosure additionally presents a facile technique for the direct synthesis of PANI nanotubes, with rectangular pores, on chemically activated CC.
