Synthesis of Poly(3,4-ethylenedioxythiophene)–Platinum and Poly(3,4-ethylenedioxythiophene)–Poly(styrenesulfonate) Hybrid Fibers by Alternating Current Bipolar Electropolymerization

Alternating current (ac) bipolar electropolymerization of 3,4-ethylenedioxythiophene (EDOT) was performed in the presence of hexachloroplatinate ([PtCl6]2–) or poly(styrenesulfonate) (PSS). We demonstrated that both [PtCl6]2– and PSS were successfully incorporated into electrogenerated poly(3,4-ethylenedioxythiophene) (PEDOT) as dopants to offer hybrid fibers composed of (i) PEDOT and platinum nanoparticles (PtNPs) (PEDOT–Pt hybrid fibers) and (ii) PEDOT and PSS (PEDOT–PSS hybrid fibers), respectively, in one step, grown from the very edges of Au wires used as bipolar electrodes (BPEs).
