Production of materials with periodically arranged microparticles by photopolymerization of patterns formed at parametric excitation of capillary surface waves

摘要

It is experimentally demonstrated that parametric excitation of capillary waves in a liquid polymer can result in a spatially periodic distribution of microparticles. The distribution of the particles follows the pattern of the waves excited on the surface of the liquid. It is shown that photopolymerization allows positions of microparticles to be fixed and materials with controlled spatially periodic inhomogeneity to be produced.
