微孔壳结构PS核壳模板制备导电聚合物包覆复合微球

摘要

In this paper,polystyrene (PS)core-shell template particles with microchannels in shell were pre-pared through seed-polymerization by using mixed monomers of styrene (St)and divinyl benzene (DVB)with PS seeds emulsion firstly.Using the template particles,organic conductive polymers(OCPs)-coated PS com-posite particles were synthesized under capillary force through solution polymerization of polypyrrole (PPy)and polyaniline (PANI),and the conductivity of the particles was about 5.5×10-5S/cm.Furthermore,the nano-composite particle of PS/PTh was synthesized using thiophene(Th)chemical oxidative polymerization through phase transfer catalysis method.The overlayers of the core-shell PS/PTh composite spheres have diverse sur-face morphology.%首先借助种子乳液聚合手段，以苯乙烯、二乙烯苯为混合单体，在致孔剂存在下制备出壳具有微通道的聚苯乙烯核壳结构模板微球。利用该模板，通过毛细管力对导电聚合物单体进行充分吸附，利用溶液聚合制备了表面包覆均匀的有机导电聚合物(聚吡咯、聚苯胺)包覆聚苯乙烯复合微球，导电率达到5.5×10-5 S/cm左右。并成功利用水溶性很差、且在水体系中难以聚合的噻吩单体，通过相转移催化实现了对模板微球的包覆，得到表面形貌独特的聚噻吩包覆聚苯乙烯复合微球。
