摘要
利用垂直沉积自组装技术在氧化铟锡（ITO）导电玻璃基底上制备出高度有序的聚苯乙烯（PS）薄膜，以此为模板，在三电极体系中应用循环伏安法，控制电势在-0．3-0．9V之间，以20mV／S的扫描速度，在有序排列PS薄膜的表面电化学沉积聚苯胺（PANI），成功制备出了聚苯胺／聚苯乙烯（PS／PANI）有序导电高分子复合材料，通过紫外-可见光分光光度计、循环伏安法、场发射扫描电镜、x射线衍射仪进行表征，结果表明，制得的PS／PANI复合材料粒径均匀、排列有序、呈密堆积结构，可为制备具有有序中空或大孔膜产物提供较理想的模板。
The highly ordered thin films of polystyrene（PS） were prepared on indium tin oxide（ITO） conductive glass substrate by vertical deposition self-assembly technique. As template in a three-electrode system by cyclic vohammetry, controlled potential between -0.3-0.9V, scan rate of 20mV/S in the orderly arrangement of the PS film surface electro- chemical deposition of polyaniline （PANI）, successfully prepared ordered polyaniline/polystyrene （PS/PANI） conductive polymer composites. Related characterized by UV-visible spectrophotometer, cyclic voltammetry, field emission scanning electron microscopy, X-ray diffractometer . The results showed that： the obtained PS/PANI composite had uniform size, arranged in order, showed a close-packed structure, highly ordered PS/PANI composite template technology could provided an ideal template for preparing the products which has ordered hollow or macroporous film.
