【摘要】 以聚2-丙烯酰胺-2-甲基丙磺酸(PAMPS)溶液为掺杂酸和聚合介质,合成溶解性好的聚苯胺。研究了反应体系中氧化剂、AMPS单体浓度、反应温度和反应时间等因素对聚合反应的影响,确定了适宜的工艺条件为:AMPS单体浓度40%,反应温度5℃,时间5.0h,氧化剂与苯胺的摩尔比0.6。在此条件下,产物在有机溶剂中的溶解度超过80%,在水中的溶解度高达到25.12%.产物的导电率为0.56s/cm,利用IR、扫描电镜对产物进行了表征分析。更多还原

【Abstract】 A new process for the preparation of polyaniline with good solubility, with the solution of poly (2-Acrylamide-2-methylpropane sulfonic acid) (PAMPS) as doping acid and polymerization medium, is developed in this paper. The effect factors such as the molar ratio of oxidant and PAMPS with aniline, reaction time and the post-processing on the process have been investigated. Suitable reaction conditions were determined as follows: Concentration of AMPS is 40%, reaction temperature is 5℃, reaction time is 5.0 h, mole ratio of the antioxidant to aniline is 0.6. In the condition, the solubility of the product is more than 80% in organic solvent, and 25.12% in water. The conductivity of the product is 0.56 s/cm. The product was confirmed by IR, SEM.更多还原
