本研究的目的是开发一种在自组装硅烷单层（sam）修饰的绝缘衬底上制备聚吡咯（PPy）薄膜的有效方法。用扫描电子显微镜（SEM）研究了硅烷SAMs和PPy薄膜的形貌。SEM图表明，硅烷偶联剂分子在基体表面排列均匀、有序、紧密。制备的聚吡啶薄膜在硅烷偶联剂中浸泡约10min后形貌致密均匀。介绍了硅烷的水解反应及制备钐和聚吡啶薄膜的工艺方案。利用x射线光电子能谱（XPS）对PPy薄膜进行化学分析。所研究的聚吡啶薄膜在电磁干扰屏蔽和固体电解电容器方面具有潜在的应用前景。
The objective of this study is to develop an effective method for the preparation of polypyrrole (PPy) films on insulating substrates modified by self-assembled silane monolayers (SAMs). The morphology of silane SAMs and PPy films was investigated using scanning electron microscopy (SEM). The SEM pattern of SAMs showed that silane coupling agent molecules were arranged uniformly, orderly and tightly on the surface of substrate. The as-prepared PPy films exhibited the compact and uniform morphology when the substrates were dipped in silane coupling agent for about 10min. The hydrolysis of silane and deposition process scheme of SAMs and PPy films were described. Chemical analysis of PPy films was performed by X-ray photoelectron spectroscopy (XPS). The studied PPy films showed potential applications in electromagnetic interference shielding and solid electrolytic capacitor.
