Polystyrene-block-polybutadiene(PS-b-PB) microporous polymer honeycomb films with hexagonal pores were prepared by solvent evaporating self-organization under humid conditions(polystyrene-blockpolybutadiene,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.
