【摘要】 该文以十二烷基苯磺酸与柠檬酸复合掺杂剂制备聚苯胺,对聚苯胺的电导率、溶解性、电致变色性能进行了研究,采用循环伏安法、红外光谱、热重对聚苯胺进行了表征,结果表明,柠檬酸与十二烷基苯磺酸摩尔比为1∶1时,聚苯胺的电导率最大,可达6.67 S/cm;二者摩尔比为0.25∶1时,聚苯胺在二甲苯中的溶解度为1.475 8 g,在1.5 V电压下变色均匀,响应时间短,可实现黄—黄绿—绿—蓝—深蓝范围内的可逆变色。更多还原

【Abstract】 Polyaniline doped with dodecylbenzenesulfonic acid(DBSA) and citric acid was prepared and characterized by means of CV,thermogravimetric analysis and FTIR.The conductivity,solubility and electrochromism of polyaniline were studied.The results show that,when the molar ratio of DBSA to citric acid is 1∶ 1,the conductivity reaches the maximum,which is 6.67 S/cm.When the molar ratio of DBSA to citric acid is 0.25∶ 1,the solubility of polyaniline in dimethylbenzene is 1.475 8 g and can realize uniform electrochromism at-1.5~1.5 V voltages.The electrochromic range is yellow-yellow green-green-blue-deep blue with short response time and the change is reversible.更多还原
