摘要/Abstract

摘要： 利用溶剂散逸自组装法在潮湿的条件下，制备了聚苯乙烯-聚丁二烯嵌段聚合物（PS-b-PB）有序多孔膜。利用聚乙烯可收缩膜将PS-b-PB多孔膜进行两次收缩，形成小孔径的有序多孔膜。通过收缩，膜上的孔由圆形变为长方形或者梭形，孔的尺寸从微米级收缩至亚微米级。利用扫描电子显微镜对膜收缩过程中2种形状产生的机理进行了研究。结果表明，PS-b-PB结合了聚苯乙烯（PS）和聚丁二烯（PB）两个均聚物的优点，收缩后仍然保持膜结构的平整性，从而将不可见的热场变化转变为可见的光学变化。

Abstract: Polystyrene-block-polybutadiene(PS-b-PB) microporous polymer honeycomb films with hexagonal pores were prepared by solvent evaporating self- organization under humid conditions (Polystyrene-block-polybutadiene, referred to as: PS-b-PB, the same below). The PS-b-PB honeycomb films were shrunk twice by using polythene shrinkable films to form ordered porous film with small pores. The pores in film changed from circular to rectangular or fusiform after shrinkage; the pore size of film was shrunk from micron into submicron. Scanning electron microscopy (SEM) was used to study the generation mechanism of two films. The results showed that PS-b-PB could transform the invisible thermal field signals into visible optical signals based on the advantages combination of polystyrene and polybutadiene which flat films structure remained after contraction.

Key words: solvent evaporation self-assembly, polystyrene-block-polybutadiene, microporous polymer honeycomb films, shrunk
