DURABLE ANTIREFLECTIVE FILM WITH SURFACE MODIFIED INORGANIC NANOPARTICLES

摘要

Antireflective films are described having a surface layer comprising a the reaction product of a polymerizable low refractive index composition comprising at least one free-radically polymerizable fluoropolymer and surface modified inorganic nanoparticles. A high refractive index layer is coupled to the low refractive index layer. In one embodiment, the high refractive index layer comprises surface modified inorganic nanoparticles dispersed in a crosslinked organic material. The antireflective film is preferably durable, exhibiting a haze of less than 1.0% after 25 wipes with steel wool using a 3.2 cm mandrel and a mass of 1000 grams.
