Abstract

In this report, we present a novel and simple method of fabricating robust, anisotropic, and patterned honeycomb and pincushion films by photo-cross-linking of poly(1,2-butadiene) (PB). We show that honeycomb films can be prepared by casting a solution of an amphiphilic polymer and a hydrophobic polymer under humid conditions. Thermally and chemically stable PB honeycomb films, which exhibit high water repellency, can be fabricated by irradiation of UV light. The patterning of honeycomb and pincushion films can be performed by heat treatment after UV light irradiation through a photomask. Furthermore, anisotropic honeycomb and pincushion films can be prepared by stretching.
