摘要 以过硫酸钠为氧化剂,在木质素磺酸(LS)水溶液中通过化学氧化法聚合3,4-乙撑二氧噻吩(PEDOT),制备聚(3,4-乙撑二氧噻吩)/木质素磺酸(PEDOT/LS)水分散液。研究了木质素磺酸用量、氧化剂添加量、pH值、固含量和反应温度对产物PEDOT/LS的粒径及导电性的影响。实验得出较佳的反应条件是:木质素磺酸与EDOT单体质量比为2.0~2.5:1,氧化剂与EDOT摩尔比为1.3:1,反应体系pH值约1.5,固含量在1.8%~2.5%,反应温度10~20℃。用PEDOT/LS配制得到的涂层,表面电阻小于10^8Ω.sq^-1,光滑透明且附着力达到二级,满足抗静电剂的要求。 Poly(3,4-ethylenedioxythiophene)(PEDOT) was synthesized in lignosulfonic acid (LS) solution using sodium persulfate (Na2S2O8) as an oxidant to prepare PEDOT/LS aqueous dispersion. The effects of LS and Na2S2O8 weight ratio, pH value, solid content and temperature on PEDOT/LS particle size and conductivity were studied. The optimized polymerization conditions were found as follows: LS to EDOT weight ratio = 2.0-2.5, Na2S2O8 to EDOT molar ratio = 1.3:1, pH =1.5, solid content percentage = 1.8%-2.5% and temperature = 10-20℃. The surface resistance of the prepared PEDOT/LS coating is lower than 10^8Ω.sq^-1, and the coating is smooth and transparent with 2ed-grade adhesion, which can be used as antistatic agents.
