A simple method to fabricate colloidal thin films with periodical structures was investigated. In this study, poly(N-isopropylacrylamide) (PNIPAM) microgel and polystyrene particles with PNIPAM chains on the surface (hairy particles) are used as components. Aqueous dispersions of these PNIPAM-carrying particles spontaneously form monolayers as water evaporates. After the medium is completely evaporated, periodical structures remain on the substrate. This paper focuses on the effect of graft chain density of the hairy particles on film formation.

    Strong dependence of surface residence time of a planar organic molecule (hydrogen phthalocyanine) on vicinal surfaces of hydrogen-terminated Si(111) was observed in pulsed molecular beam scattering experiments. These results can be explained by the difference in the microscopic contact area of...
