摘要

Three-armed poly(styrene sulfonate) derivatives (PSS-T) was synthesized by atom transfer radical polymerization (ATRP) and used as dopants for the preparation of star-shaped PEDOT:PSS-T composites. From their loosed packing structure, reduced graphene oxide (rGO) was well doped into the PEDOT:PSS-T composites resulted in improved dispersion properties and enhanced electrical performance. The cyclic stability of supercapacitors using PEDOT:PSS-T/rGO composites showed 95.5% capacitance retention after 10,000 charge/discharge cycles which is superior than its devices using of commercial PEDOT:PSS/rGO composites.
