| 摘 要： | 以二丁基萘磺酸(DBNSA)或十二烷基苯磺酸(DBSA)为有机酸,水为主要反应介质的条件下进行沉淀聚合直接制备有机酸掺杂的聚苯胺(PAn).讨论了酸度、温度和氧化剂用量等反应条件对产物的影响。2L规模扩大实验的产率约为75%～80%,所得PAn具有高电导率(3.0S·cm-1),并易溶于普通有机溶剂。其中PAn-DBNSA在各方面较具优势。

| Abstract: | Polyanilines doped with different organic acids were directly prepared by precipitation polymerization technique using water/acetone as the medium of reaction and dodecylbenzene sulfonic acid (DBSA) or dibutylnaphthalene sulfonic acid(DBNSA) as the organic acid. Optimum reaction parameters, such as polymerization temperature, reaction time, molar ratio of acid/aniline and (NH4)2S2O8/aniline, were obtained for the precipitation polymerization of aniline. Polymer yield was about 80%. Organic acid doped PAn made in 2L experiment scale showed a high conductivity (3.0 S·cm-1) and can be easily dissolved in common organic solvent, therefore, this precipitation polymerization technique should be applied in industry. PAn DBNSAis somewhat better than PAn DBSA in properties. |
