Abstract:
1. A process for producing colloidal crystals immobilized with a polymer, comprising the steps of: preparing a monomer-dispersion in which colloidal crystals having a three-dimensionally ordered array state are formed by adding, to a monomer-containing liquid containing at least one kind of monomers, colloidal particles having an average particle size in a range from 0.01 μm to 10 μm and a degree of monodispersity expressed by a following equation (1) of 20% or below, and then by dispersing the colloidal particles so as to arrange the colloidal particles in a three-dimensionally ordered array state at which a reflection spectrum thereof exhibits a reflection peak; and obtaining the colloidal crystals immobilized with a polymer by polymerizing the monomers in the monomer-dispersion, wherein, in the step of preparing a monomer-dispersion, the colloidal particles are dispersed in the monomer containing liquid by applying ultrasound.
