摘要

Abstract

Poly(styrenesulfonate)-poly(ethylene glycol)(PSS-MPEG)copolymers were prepared by using methoxypolyethylene glycol（MPEG)

isophorone diisocyanate（IPDI)

hydroxypropyl acrylate（HPA)

and styrene sulfonic sodium（SSS)as raw materials.The resulting copolymers were characterized by Fourier transform infrared spectroscopy（FTIR)

proton nuclear magnetic resonance（1H NMR)and gel permeation chromatography（GPC).The copolymer had a molecular weight between 40000—140000. Poly(3

4-ethylenedidxythiophene)(PEDOT)/PSS-MPEG aqueous dispersions were then synthesized by chemical oxidation using copolymer PSS-MPEG as the template and dopant.The kinetics of EDOT polymerization was investigated with gas chromatography（GC).Ultra-violet visible absorption

thermal stability and sheet resistance of the films of PEDOT/PSS-MPEG were investigated.The PEDOT dispersion with MPEG showed larger particle sizes than that of PEDOT/PSS.The PEDOT/PSS-MPEG dispersion showed better film formability and gave a smoother surface of the film than that of PEDOT/PSS.It was also found that the film of PEDOT/PSS-MPEG had a lower sheet resistance

which might be due to that PEDOT/PSS-MPEG provided a better film with less defects and MPEG improved the compatibility of PEDOT and PSS phases.
