采用溶剂散逸自组装制备了聚丁二烯(PB)有序多孔膜.水珠能在冷的高分子溶液表面凝结形成有序的阵列,溶剂蒸发后,高分子材料按照水珠排列的形貌形成了有序多孔膜.两性共聚物的加入能够起到稳定水滴的作用,从而确保多孔膜成为有序的结构.利用聚乙烯可收缩膜将聚丁二烯多孔膜收缩2次,得到长方形、梭形、条形和哑铃形的孔.孔的尺寸从微米级收缩至亚微米级,并对产生各种形状的机理进行了研究.

Microporous polymer honeycomb films with hexagonal pores were prepared by self-organization under humid conditions. The amphiphilic polymer acted as a stabilizer of condensed water droplets and prevented water droplets from fusion. The honeycomb film was shrunk by a shrinkable film. Various shapes could be formed upon the mechanical shrink deformation of hexagonal micro polymer meshes. Shapes such as rectangle,shuttle,slot and dumbbell were found in the shrunk honeycomb films. The pore size of honeycomb structure film (4～8 μm) was also shrunk to 130 nm. The deformation mechanism of the film was discussed.
