Abstract

We demonstrate a facile method for preparing a novel nanoporous material with an isotropic, three-dimensionally continuous pore structure from a polymeric bicontinuous microemulsion precursor, which consists of two immiscible homopolymers and the corresponding diblock copolymer. The protocol for the generation of nanopores is selective cross-linking of one domain with the subsequent removal of the other domain by solvent dissolution.

摘要

我们展示了一种简便的方法，可从由两种互不相溶的均聚物和相应的二嵌段共聚物组成的聚合物双连续微乳液前体中制备具有各向同性、三维连续孔结构的新型纳米多孔材料。纳米孔生成的方案是一个域的选择性交联，随后通过溶剂溶解去除另一个域。
