  • Abstract This study uses the combination of block copolymer and metal nanoparticles to array ordered structure and specific physical properties such as optics, electricity and magnetism. In this first part, 2-phenylethanethiol was used as the monolayer-protected gold nanoparticles (nps) and dispersed in block copolymer PS-b-PB-E thin film. Two different methods are compared, the first method was PS-b-PB-E thin film by partial crosslinked treatment then the 2-phenylethanethiol of monolayer-protected gold nanoparticles soaked into PS-b-PB-E thin film. The second method was blended gold nps within PS-b-PB-E directly. We found that the first method was better than second method which had arrangement dispersedly. The analyses of UV-VIS, TEM, and SAXS measurement are able to provide the positive evidence to characterize the dispersion of gold nps in diblock copolymer thin film.
    In the second part, we design to manufacture the multi-nanoholes golden electrode, which has many application in catalysis, selective transit function and fuel cell electrode. We use the PS-b-PB-E copolymer as the spherical micelle, which is the templates and then micelle surface reaction in mercaptane (S-H) function. Gold nps will use the exchange stabilizing ligands method in the micelle surface layer, and the porous gold electrode material by way of the heat treatment step.
