Imparting Anti-Fingerprint Properties to Moth-Eye Films Using Fingerprint Oils Absorbing Coating Materials

抄録

We have developed novel coating materials capable of absorbing fingerprint oils over time. When touch screens are operated with fingers, these oils adhere to the surface, rendering them visibly dirty. When finger oils adhere to anti-reflective coatings and structures, such as moth-eye films, their anti-reflective efficacy is substantially compromised. Specifically, in moth-eye films, the oils penetrate the grooves of the bell-shaped array and are difficult to remove. In this paper, we discuss our investigation into a technique for developing anti-fingerprint properties using these novel coating materials.
