摘　　要：采用实验室合成的结点处带有三硫酯基团的嵌段共聚物PS-b-PEO为原料,通过水滴模板法制备得到六方排列的蜂窝状有序多孔膜。比较不同溶剂,四氢呋喃(THF)、二氯甲烷(CH2Cl2)、氯仿(CHCl3)、二硫化碳(CS2),对有序多孔膜的影响。采用NaBH4处理有序多孔膜,是使有序多孔膜孔的边缘出现可与金相互作用的巯基,之后通过原位制备纳米金的方法,将纳米金颗粒负载到多孔膜孔的边缘,实现纳米金颗粒的有序排列。Strictly ordered and closely packed nano-and micro-porous film was prepared through breath figure(BF) technique with block copolymer PS-b-PEO with trithiocarbonate bearing at the junction synthesized in lab as raw material. It is studied how solvents(THF, CH2Cl2, CHCl3, CS2)influence films morphology. NaBH4 was used to treat these films, and thiol group appeared at the edge of the porous. Gold nanoparticles were attached to the edge of the porous through preparation in situ.
