%X Hybrids consisting of a microporous film and polymeric microspheres were fabricated via a simple
method without a special apparatus. Highly ordered microporous polymer films with honeycomb
structure were fabricated by a dissipative process utilizing amphiphilic poly(acrylic acid)-
block-polystyrene, which was synthesized by atom transfer radical polymerization followed by an
acid-catalyzed ester cleavage reaction. In order to embed the microsphere efficiently, the dried microporous
films should be soaked in methanol to alter the surface functionality and to improve the
wettability of the film surface. The introduction of amino functionality to polystyrene microspheres
by seeded polymerization of N,N-dimethylaminoethyl methacrylate drastically improved the embedding
efficiency. The effect of open pore size was also investigated.
