摘要/Abstract

摘要： 从硝基重氮树脂(NDR)与包裹巯基乙酸的铂纳米颗粒(MA-PtNP)的静电自组装,制备了感光性的自组装多层超薄膜.经选择性紫外曝光和十二烷基硫酸钠(SDS)水溶液显影,光照部分的膜,因层与层之间的离子键转变为共价键,不再被SDS水溶液洗脱而留下来;未光照部分的膜,层与层之间仍是离子键,在显影时被除去,从而形成图像.用AFM和SEM对形成的图像进行了表征.

关键词: 硝基重氮树脂, 铂纳米颗粒, 静电自组装, 微图像

Abstract: The photosensitive ultra-thin multilayer films were fabricated via self-assembly of Pt nanoparticles capped with mercaptoacetic acid (MA-PtNP) and nitro-substituted diazoresin(NDR). By means of selective exposure under UV light and developing in SDS aqueous solution the exposed regions of the film,in which the bond nature of the film has been converted from ionic to covalent,are not removed and are kept completely on the substrate,however the un-irradiated parts of the film can be removed completely to form fine images. The formed images were characterized with AFM and SEM.

Key words: nitro-substituted diazoresin, Pt nanoparticles, electrostatic self-assembly, micropatterning
