Hierarchical structured sol–gel coating by laser textured template imprinting for surface superhydrophobicity
Abstract
This paper reports a fabrication method generating biomimetic hierarchical structures simulating the lotus leaf’s surface resulting in superhydrophobicity and self-cleaning functions. The surface micro-patterns were imprinted on a hard sol–gel protective coating by a template made by the laser direct ablation technique. Bump structures were precisely controlled. The nano-structures were superimposed by self-assembled surface modified
