Abstract

Abstract:

Micro-structure surfaces have excellent performances in waterproof self-purification and drag reduction. However, current approaches for preparation of hydrophobic surfaces are complex and not systematic, limiting their further development and wider application. From the perspective of engineering preparation, this paper summarizes the classical theoretical models for the design of micro-structure surfaces and the theoretical studies on the geometrical design of microstructures at home and abroad. Intrinsic contact angle of common engineering materials through balance force analysis and computational simulation, determining the size of hydrophobic microstructure, the shape of the cross section is explored. Section line length and two size coefficients of designing hydrophobic microstructure and summarize the design process of hydrophobic microstructures are put forward, providing a theoretical foundation for the preparation of hydrophobic microstructure or mould.

Key words: micro-structure, bionic, super-hydrophobic, design method, geometric shape
