Nanoporous epoxy with gyroid texture is fabricated by using a nanoporous polymer with gyroid-forming nanochannels as a template for polymerization of epoxy. The nanoporous polymer template is obtained from the self-assembly of degradable block copolymer, polystyrene-b-poly(l-lactide) (PS-PLLA), followed by hydrolysis of PLLA blocks. Templated polymerization can be conducted under ambient conditions to create well-defined, bicontinuous epoxy networks in a PS matrix. By taking advantage of multistep curing of epoxy, well-ordered robust nanoporous epoxy can be obtained after removal of PS template, giving robust porous materials. The through-hole nanoporous epoxy in the film state can be used as a coated layer to enhance the adsorbability for both lysozyme and bovine serum albumin.
通过使用具有向列型纳米通道的纳米多孔聚合物作为聚合环氧树脂的模板，制备了具有向列型纹理的纳米多孔环氧树脂。纳米多孔聚合物模板是通过可降解嵌段共聚物聚苯乙烯-b-聚（L-丙交酯）（PS-PLLA）的自组装，然后水解 PLLA 嵌段得到的。模板聚合可以在环境条件下进行，以在 PS 基体中形成具有良好定义的双连续环氧树脂网络。通过利用环氧树脂的多步固化，可以在去除 PS 模板后得到有序的、坚固的纳米多孔环氧树脂，从而得到坚固的多孔材料。薄膜状态下的贯穿孔纳米多孔环氧树脂可用作涂层，以提高对溶菌酶和牛血清白蛋白的吸附能力。
