hdi三聚体改性聚氨酯/聚吡咯复合材料的制备及导电性能
Keywords: 复合材料,有机硅聚氨酯,原位吸附聚合,导电性能
Abstract:
？采用原位吸附聚合法制备导电有机硅聚氨酯复合材料(ppy/heso),研究了投料比、投料顺序及反应条件等对ppy/heso导电性能的影响。结果表明:吡咯用量为12.5%、fecl3、蒽醌--2--磺酸钠与吡咯摩尔比为2.2:1.2:1、投料顺序为heso一吡咯一蒽醌--2--磺酸钠一fecl3、反应温度为0℃、eso乳液的ph值=3时,制备出的ppy/heso复合材料导电性能最佳。heso乳胶中的si与导电聚吡咯具有协同效果,利于聚吡咯与heso乳胶形成互通导电构型,在heso乳胶表面或界面处形成连续核壳型导电聚合物。
