通过图案化自组装膜导向的电沉积制备了聚吡咯(PPy)微结构.由微接触印刷方法制备图案化自组装膜并作为电沉积的模板.研究发现,自组装膜在导向电沉积中在不同的基底上具有不同的作用:在十二烷基硫醇(DDT)、十八烷基硫醇(ODT)修饰的金基底上和十八烷基三氯硅烷(OTS)修饰的铟锡氧化物玻璃上(ITO),电沉积主要发生在自组装膜未修饰区,而在半导体单晶硅表面,PPy沉积在OTS修饰区,是基底表面的导电性及PPy与基底表面基团相容性共同作用的结果.
Polypyrrole (PPy) microstructures were prepared by patterned self-assembled film-directed electrodeposition.Patternized self-assembled films were prepared by microcontact printing method and used as templates for electrodeposition.It was found that self- Different substrates have different effects: indium tin oxide modified with dodecyl mercaptan (DDT), octadecyl mercaptan (ODT) modified gold substrate and octadecyl trichlorosilane (OTS) On glass (ITO), electrodeposition mainly occurs in the unmodified area of the self-assembled film. On the surface of the semiconductor single crystal, PPy is deposited in the OTS modified area, which is the conductivity of the substrate surface and the compatibility of PPy with the surface group of the substrate Result of joint action.
