【摘要】 以马来酸酐-醋酸乙烯共聚物乳液微球(250~400 nm)为模板,苯乙烯为单体,制备了表面多孔化的聚苯乙烯(PS)基材。通过将模板放置于不同的位置,在PS表面特定区域内形成了若干个宏观排列规整的微观孔群。采用电子扫描显微镜观察孔的表面及内部形貌,结果表明:80℃下用水作脱模剂可完全脱除模板,制备工艺简单,环境友好。更多还原

【Abstract】 Polystyrene(PS) substrate with porous on the surface was fabricated by templating against maleic anhydride/vinyl acetate copolymer microspheres(250～400?nm).By arranging templates microspheres in limited regions,the PS substrate with arranged pores on the surface was obtained conveniently.The morphologies of pores were characterized by scanning electronic micrograph(SEM).The results show that the templates can be removed with deionized water(80?℃) completely and the process is simple and environmental friendly.更多还原
