Problems solved by technology

However, since van der Waals force and hydrogen bond are physical bonds, the force is weak, and the surface active hydroxyl groups of the glass substrate without pretreatment are less, and the dehydration condensation reaction between the surface active hydroxyl groups of the glass substrate and the surface hydroxyl groups of the silica sol requires high temperature heating treatment so that few Si-O-Si bonds are formed
Therefore, the adhesion of the anti-reflection film on the surface of the glass substrate is not good, so that the hardness and friction resistance of the anti-reflection film are poor, and the anti-reflection film is easy to fall off in the aging environment, resulting in the deterioration of the anti-reflection film. Permeable failure
