摘　　要：采用分散聚合体系,在聚酰亚胺(PI)基体表面原位沉积聚苯胺(PANI)制备高导电的PANI/PI/PANI复合膜。结果表明,空间稳定剂聚乙烯吡咯烷酮(PVP)对PANI粒子的稳定效应主要对大粒子起稳定作用;基体表面致密膜层主要由PANI小粒子堆砌形成。基体表面为质子酸(盐酸)掺杂的PANI膜层,膜中不含有PVP。采用高相对分子质量PVP作为稳定剂、增大PVP浓度可使复合膜表面结构致密。Polyaniline/Polyamide （PANI/PI） compound films with a high conductivity were prepared by in-situ depositing PANI on PI matrix in a dispersion polymerization system. The results show that stabilization of space stabilizer polyvinylpyrrolidones （PVP） is mainly effect on the larger PANI particles. The compact film growing on PI matrix is mostly formed by smaller PANI particles. The films formed on PI matrix are proton acid （HCl） doped PANI without space stabilizer PVP. Adopting PVP of a higher relative molecular mass and increasing PVP concentration can form a more compact surface structure.
