A simple and facile method to fabricate porous films which were locally patterned by heteropoly acid was developed in this study. The mixture of poly(methyl methacrylate) and stabilizer dichloromethane solution which contains heteropoly acid aqueous solution, prepared through shaking, was applied to fabricate a reversed microemulsion. After spreading and evaporating the solvent of microemulsion on a glass slide, an ordered honeycomb film was produced by incorporation of heteropoly acid in the cavities. The locally anchored heteropoly acid could be readily applied for the selective modification of the porous films through the chemical reactions in the cavities with the additive agents. The silver nanoparticles were prepared the reduction of silver ions by reduced state HPWO, and the polypyrrole spheres were locally obtained through the oxidative polymerization of pyrrole catalyzed by HPMoO in the cavities. Considering that water-soluble molecules and nanoparticles were universally suitable for the present strategy, the reported approach opened up an efficient way for patterning organically incompatible components on porous polymer films the assembly of microemulsion droplet carriers to fabricate multi-functional hybrid surface structures.
本研究开发了一种简单易行的方法来制备由杂多酸局部图案化的多孔膜。通过振荡制备含有杂多酸水溶液的聚甲基丙烯酸甲酯和稳定剂二氯甲烷溶液的混合物，用于制备反相微乳液。在将微乳液的溶剂铺展并蒸发在载玻片上后，通过在空腔中掺入杂多酸制备出有序的蜂窝状膜。局部锚定的杂多酸可通过与添加剂在空腔中的化学反应轻松用于多孔膜的选择性修饰。通过还原态的HPWO还原银离子制备银纳米颗粒，并通过空腔中HPMoO催化的吡咯氧化聚合局部获得聚吡咯球。考虑到水溶性分子和纳米颗粒普遍适用于本策略，所报道的方法为在多孔聚合物膜上图案化有机不相容组分开辟了一条有效途径，即通过微乳液滴载体的组装来制造多功能混合表面结构。
