【摘要】 采用不同比例的十二烷基苯磺酸(DBSA)与对甲基苯磺酸(TSA)复合磺酸体系替代盐酸体系,合成了具有一定溶解率的聚苯胺(PANI),研究了不同DBSA/TSA比例对掺杂态PANI的产率、掺杂程度、溶解率和电导率的影响。结果表明,DBSA/TSA摩尔比为7/3时所得PANI同时具有较好的电导率和溶解性。采用该体系合成的掺杂态PANI的电导率为1.1S/cm,在N甲基吡咯烷酮(NMP)、丙酮、四氯化碳和二甲苯中的溶解率(质量分数)分别为70%,40%,26%和19%。更多还原

【Abstract】 A new synthesizing technique, i.e. by using of a multiple acids system of dodecylbenzene sulfonic acid (DBSA) and p-toluene sulfonic acid (TSA) as the synthesizing media for in-situ preparation of polyaniline (PANI) instead of the conventional hydrochloride acid, was brought forward in order to enhance the solubility of PANI without losing the conductivity. The yield, the doping level, the solubility and the conductivity of the as-prepared PANI were investigated. By properly adjusting the molar ratio of DBSA/TSA in the synthesizing media, a PANI with conductivity of 1.1S/cm and solubility (mass fraction) of 70% in NMP, 40%in acetone, 26%in carbon tetrachloride and 19 % in xylene was obtained.更多还原
