| Research Abstract |
For the design and optimization of coating process of nanoparticles/polymer composite thin films and their devise manufacturing, solvent evaporation from the films and dewetting dynamics of the films during thermal annealing were observed, and the relationship between these phenomena and the spatial structure of nanoparticles in the films was investigated. The evaporation rate of organic solvent from the film was strongly affected by the presence of nanopraticles. The dewetting was suppressed by adding nanoparticles which segregated to the film surface. Brownian dynamics simulations suggested that the dispersion state of nanoparticles in solvent depends on the combination of solvent and organic molecules to modify the nanoparticle surface.
