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
