【摘要】 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5.5×10-5S/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。更多还原

【Abstract】 In this paper,polystyrene( PS) core-shell template particles with microchannels in shell were prepared 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 composite 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 nanocomposite 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 surface morphology.更多还原
