Research Progress on Preparation of Superhydrophobic Materials by Laser Etching

Laser etching uses a contactless process, which is simple, reliable and environmentally friendly. The laser processing of both metallic and non-metallic materials was reviewed. The concept of superhydrophobic surfaces and the principles of laser etching were firstly outlined, the current state of research in China and abroad was summarized, and finally, the feasible suggestions for future research directions were made to provide a reference for future research directions in the preparation of superhydrophobic surface by laser etching.
