Abstract

Patterned "bead in pore" composite film with hemispherical or mushroomlike TiO(2) microparticles lying in the holes of a honeycomblike polystyrene matrix has been fabricated by a template-free bottom-up approach from a homogeneous solution of TiCl(4)/polystyrene/CHCl(3) using the breath figures method. It is a very simple way to prepare hemispherical or mushroomlike TiO(2) microparticles and to get the hexagonally nonclose-packed arrays of asymmetrical particles with or without polymer matrix, which have potential applications in photonics.
