The nanopattern was fabricated by ultraviolet nanoimprint lithography (UV-NIL) on a transparent film using an UV curable resin. In this study, a moth-eye structure, which is used for anti-reflection, on a glassy carbon substrate was used as a master mold. Furthermore, a nanopattern made of the UV curable resin via UV-NIL was also used as a replica mold, and we succeeded in fabrication of a second generation nanopatterned film. Using both obtained transparent films with nanopattern, the evaporation characteristics of a water droplet were investigated. As a result, it became clear that the speed of evaporation on the first and second generation films was improved, compared to the substrate without the nanopattern. Moreover, the nanopatterned surface has a lower reflectance ratio than the planar surface. Consequently, the obtained film can be a multifunctional transparent film to prevent the light reflection and improve the evaporation rate of water droplet. %8 2018-02-09
