Abstract

Surfaces of lotus leaf and moth eye have fine structures. The structure produces water repellent effect or reflection suppression. The purpose of this study is to reproduce these characteristic to the artificial material surface by using a precision machining method. Micro slurry-jet erosion has been proposed as the precision machining method for a glass or plastic surface. The micro slurry-jet erosion method is a wet blasting technique which used alumina particles as the abrasive medium along with compressed air and water to create the fine structures. The glass surface processed has a hydrophobic character and do not show influence of the light transmission property. These results concluded that the precision machining method was one of the promising method to create the bio-inspired surface on the artificial materials.
