Abstract:
The present invention relates to an article comprising a substrate having a main surface coated with a mesoporous antistatic coating, said coating having a refractive index lower than or equal to 1.5, and a silica based matrix functionalized by ammonium groups, said matrix having a hydrophobic character. Under certain conditions, the mesoporous antistatic coating is a single-layer anti-reflection coating or is part of a multi-layer anti-reflection coating.This invention further relates to a method for manufacturing said article, and to the use of a mesoporous coating having a silica based matrix functionalized by ammonium groups, as an antistatic coating.
