Outline of Final Research Achievements

It is necessary to develop technology for nanoparticles arrangement using a regularly arranged nano-holes-pattern in order to create the innovative functional material, such as metamaterials. In this study, using the properties of supercritical fluids, we aimed to develop a nano-patterning method for hybrid nanoparticles into nano-holes printed on a polycarbonate sheet. The cross-linked nanoparticles (X-NPs) were synthesized to maintain the shape under processing and were dispersed into a supercritical fluid phase having a entrainer. We found that it was possible to introduce a part of X-NPs into the nano-holes. However, we could not achieve an embedding the XPS-NPs uniformly into the holes spread on the sheet. Although we could not make of a partial metallized nanoparticle to make special morphology with directionality interaction in the research period, we'd like also to continue this research to achieve the purpose described in original plan.
