Abstract:

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.
