采用分散聚合方法在玻璃基体表面制备得表面光滑聚苯胺(PANI)导电膜。采用扫描电子显微镜(SEM)研究氧化刺过硫酸铵(APS)加入方式、质子酸环境对制得膜形貌的影响。通过紫外光谱和红外光谱分析玻璃基体表面导电PANI膜的结构。结果发现:采用滴加APS方式可制得致密PANI膜;本身黏度较大的无机含氧酸(高氯酸、磷酸)与PVP稳定剂并用时会使体系黏度增大,无法制得导电薄膜(高氯酸、PVP体系)或只能得到有缺限的膜(磷酸、PVP体系)。紫外分析证实玻璃基体表面是掺杂态PANI膜,红外分析表明PANI膜结构中不合有稳定剂PVP。膜的电导率数量级在10^-3S/cm,电导率高低与形貌好坏存在一致性。
The smooth electroconductive PANI films on glass matrix were prepared by an in-situ dispersion polymerization method. The effects of oxidant APS immitting methods and proton environment on film appearance were studied through SEM ahservation. The PANI film structure on glass matrix was characterized by UV and IR. It was indicatesd that dense PANI film could be achieved in a method dripping APS onto the system. That Acid with high viscosity like HClO4,H3PO4 were used along with PVP would enlarge the system viscosity,and high surface quility PANI films could not be achieved (HClO4, PVP system) or only imperfect PANI films (H3PO4 ,PVP system) could be got. UV analysis indicated that it was doped PANI film on glass matrix, IR analysis indicated there was no PVP in film structure. The PANI film conductivity was in related with its surface quility,whose order of magnitude was 10^-3S/cm.
