A scalable approach for developing large area polymer films, with stimuli responsive vertically aligned nanopores is reported. Magnetic fields are used to create highly aligned hexagonally packed block copolymer cylindrical microdomains with order parameters exceeding 0.95. Selective etch removal of material yields nanoporous films which demonstrate reversible pore closure on heating.
本文报道了一种可扩展的方法，用于开发具有刺激响应性垂直排列纳米孔的大面积聚合物膜。磁场用于创建高度各向异性的六边形排列嵌段共聚物圆柱微区，其序参数超过 0.95。选择性刻蚀去除材料得到的纳米多孔膜在加热时表现出可重复的孔闭合。
