Soft materials such as liquid crystals, colloids, and polymer films have attracted many attentions as alternatives of hard materials due to its cost-effectiveness and biocompatibility. One of the most promising ways for fabrication of polymer films having highly functional properties is making nanoscale structure over the surface of films. Although various applications have been already developed by top-down process such as photolithography, molding and nano-imprinting, they still face a drawback of high cost. We have paid attention to molecular diffusion arising from ununiformed photopolymerization. In this study, we successfully formed nano-embossed structure over a polymer film through bottom-up process of photopolymerization.
