摘　　要：以导电性良好的聚苯胺作为基底,将光敏半导体材料氯化银作为引发剂,采用原位化学氧化聚合方法制备聚苯胺-氯化银纳米复合材料,并对其电学和光学性能进行系统研究。通过扫描电子显微镜、四元探针电导率测试仪,模拟太阳光照射等一系列的方法对聚苯胺单体以及聚苯胺/氯化银纳米复合材料的形貌、结构、光学性能和电导率进行了表征与比较。结果表明,聚苯胺氯化银纳米复合材料具有良好的热稳定性;纳米氯化银颗粒在聚苯胺中分散比较均匀;氯化银的掺杂会对复合材料的电导率产生积极的影响。同时,具有表面金属等离子振荡效应的氯化银掺杂在复合材料中,使该复合材料具有优异的光照吸收和催化性能。Polyaniline-silver chloride nanocomposites were prepared by in-situ chemical oxidation polymerization with polyaniline with good conductivity as substrate and photosensitive semiconductor material silver chloride as initiator,and their electrical and optical properties were systematically studied.The morphology,structure,optical properties,and conductivity of polyaniline monomer and polyaniline or silver chloride nanocomposites were characterized and compared by scanning the electron microscope,quaternary probe conductivity tester,and simulating sunlight illumination.The results show that polyaniline silver chloride nanocomposites have good thermal stability;nano-silver chloride particles are uniformly dispersed in polyaniline;the doping of silver chloride will have a positive effect on the conductivity of the composites.At the same time,silver chloride with surface metal plasma oscillation effect is doped in the composite material,which makes the composite material have excellent light absorption and catalytic performance.
