Title
(EN) Improved anti-reflective composite
(ZH) 改进的防反射复合材料
Abstract
(EN) An anti-reflective composite is provided having very high visible light transmission and negligible visible reflectance over 400 nm-800 nm wavelengths. The composite of the invention includes (a) a light transmissive substrate; (b) a hard coat deposited onto the substrate; (c) a thin carbon layer having an average thickness between about 2 ANGSTROM and about 100 ANGSTROM ; and (d) a plurality of transparent oxide layer pairs deposited onto the thin carbon layer, each transparent oxide layer pair comprising (i) a first transparent oxide having a refractive index between about 1.65 and about 2.65 and an average thickness between about 100 ANGSTROM and about 3200 ANGSTROM and (ii) a second transparent oxide layer having a refractive index between about 1.2 and about 1.85, and an average thickness between about 100 ANGSTROM and about 3200 ANGSTROM . The composite can also include an intermediate oxide layer disposed between the thin carbon layer and the first transparent oxide layer. Such intermediate oxide layer has a refractive index between about 1.5 and about 2.2 and is between 400 ANGSTROM and about 1000 ANGSTROM in thickness. In another preferred embodiment, the composite further comprises an outermost transparent low surface energy layer having a surface energy of less than about 40 dynes/cm<2>. In another preferred embodiment, the transparent layers are deposited by vacuum or non-vacuum processes or by a combination of both processes.
