Outline of Final Research Achievements

Ultra low reflectance transparent porous film attracts attention to protect sensor devices such as human eyes and cameras while suppressing reflection of light in various fields such as automatic driving technology and display for smart phones. In order to reduce the reflectance, there are two strategies: (1) diffusing light and suppressing specular reflection and making fine unevenness on the film surface. (2) A method of suppressing the reflectance by creating a layer in which the refractive index changes continuously known as the Moth-Eye effect by forming fine unevenness on the surface of the film. In this study, ultra-low reflective film was fabricated utilizing the fact that the UV curing resin applied on the polycarbonate plate crystallizes the surface layer of the polycarbonate plate and forms irregularities on the fibrils.
