Analyze the shaping characteristics of micro-cylindrical-post in manufacturing process of a superhydrophobicity film

Abstract

Superhydrophobic films (SHF) have recently increased in routine due to their non-wettable capacity. Superhydrophobicity can be occurred by making a micro-structural-post on materials with the surface having a low energy level. Thus, the shaping characteristics of the micro-structural-post should be considered. This paper analyzes the influence and evaluates the characteristics of micro-cylindrical-post having different parameters to the superhydrophobicity of PUA film. Firstly, the structure and characteristics of Polyurethane Acrylate (PUA) material are introduced. Moreover, the manufacturing process to create the micro-cylindrical-post on PUA film is illustrated. Finally, the influence of the different shaping parameters of micro-cylindrical-post on the superhydrophobicity of PUA film is evaluated and analyzed.
