摘要 以化学氧化法合成了聚(3,4-乙烯二氧噻吩)(PEDOT)水分散体,通过气相色谱法测定了EDOT聚合转化率,研究了聚合温度、模板及掺杂剂、氧化剂、催化剂等因素对EDOT聚合动力学的影响。结果表明:温度越高,聚合速率越快,但导电性能变差。在以过硫酸铵为氧化剂、硫酸铁为催化剂时,两者用量越多,EDOT聚合速率越快,硫酸铁合适的用量为2‰。模板用量越多,EDOT聚合速率越慢;EDOT在以乙烯基苯磺酸钠与丙烯酸酯共聚物为模板中的聚合速率大于以聚苯乙烯磺酸钠(PSS)为模板中的聚合速率。以共聚物为模板所制得的PEDOT水分散体,其成膜性能得到明显提高。 Poly(3,4-ethylenedioxythiophene) were synthesized by chemical oxidation method, and the kinetics of polymerization of EDOT was studied using gas chromatography (GC). The factors such as temperature, oxidant and catalyzator etc that influenced polymerization of EDOT were investigated. The results show that polymerization rate is faster when the temperature increases. When (NH4)2S2Oa and Fe2 (SO4)3 are used as the oxidation agent and catalyst respectively, the reaction rate of EDOT increases as the dosages increase. The Iron(III) p-toluenesulfonate and hydrogen peroxide show more effective on the oxidation of EDOT. The dosages and structures of templates have influences on the polymerization kinetics of EDOT as well. The polymerization rate of EDOT decreases with the amount of sodium polystyrene sulfonate (PSS) increasing. When the copolymers of styrenesulfonate and acrylates are used as the template and dopant, the polymerization rate of EDOT was faster than that using PSS as dopant. The film formality of PEDOT/PSS dispersion is improved.
