A strategy to coat a wavy 3D film on glass surface for enhancing the interface adhesion

A reverse micelle solution etching technology is proposed to generate sphere segment shaped pits on glass surface. The opening diameter of the pits is micrometer-sized. As deposition is carried out on the etched surface, the coating materials would be embedded into these sphere segment shaped pits and result in a wavy 3D film. The critical load values for the films on the etched glass are 3–4 times those for ones on the unetched glass.
