Outline of Final Research Achievements

We report that silver nanocrystals are self-assembled into ordered structures by the spatial concentration gradients created by a chemical reaction of a dispersive solvent. As a model system, we used dispersions of the silver nanowires in 2-hydroxyethyl methacrylate, HEMA. The dispersions were exposed to UV-light through a lattice-patterned photomask, to induce photopolymerization of HEMA. The silver nanowires migrated to the area in which the concentration of the poly(2-hydroxyethyl methacrylate) is low, and the size of the self-assembled structures varied with the spatial intensity distribution of the light. In addition, the sheet resistance of the resulting polymer films were influenced by the self-assembled silver nanowire structures.
