【摘要】 以化学方法水溶液合成聚苯胺，用相转化法制备聚苯胺富氧膜，系统地研究了各种聚合反应条件对聚苯胺的分子量、成膜性的影响．结果表明：在盐酸介质中，当酸浓度为3mol／m3、氧化剂与单体苯胺的摩尔比为0.5、聚合反应温度为0℃、聚合反应时间为4h时，所合成的聚苯胺分子量适中且成膜性好．更多还原

【Abstract】 Polyaniline was chemically polymerized in aqueous solutions. Polyaniline oxygen-enriched membrane was prepared by the way of phase-inversion. The effects of various synthesis parameters on the molecular weight and film-forming property of polyaniline were studied. The results show that high-quality polyaniline is synthesized over a period of 4 h under the conditions of HCL concentration at 0. 5 mol/m3,oxidant/aniline at 0. 5 and the polymerization temperature at 0 C in HCL aqueous so1utions,and its film-forming property is advantageous.更多还原
