摘　　要：采用真空蒸发沉积法,以盐酸掺杂态和本征态聚苯胺粉末为原料,分别在Si(100)和载玻片上沉积了聚苯胺膜。利用傅立叶红外光谱仪(FT-IR)和扫描电镜(SEM)对薄膜进行了表征,并研究了原料颗粒尺寸对成膜质量的影响。电导率测试结果表明,采用该方法沉积的薄膜电导率在10-6S/cm量级,达到了防静电材料电导率的要求。Polyaniline films were deposited on the substrates of Si（100） and slides by using vacuum evaporation deposition method.HCl-doped and intrinsic polyaniline powders were used as the starting material.The as-deposited films were characterized using FT-IR and SEM.The influence of the diameter of polyaniline powders on the film morphology was also analyzed.The conductivity test indicates that the conductivity of as-deposited films is about 10^-6S/cm,which can meet the need of electrostatic prevention.
