In electronic industry, many components need to be cleaned. Normally, there is cleaning process to wash components before assembly. However, it is difficult to remove all sticky contamination. One method is to make component surface to have self cleaning property. It is a surface that repelswater like a lotus leaf. A droplet can roll and grasp dust on the lotus leaf with them. Then the lotus leaf will become clean automatically. This book describes the method to mimic the microstructures of a lotus leaf by creating artificial microstructures on the surface of steel. Zinc will be deposited on steel by electroplating techniques prior to synthesizing ZnO nanorods on the zinc electroplated steel. The Zinc coating layer is varied in thickness to study the correlation between the thicknesses of the zinc layer with the ZnO nanorods grown on the steel. In this book, it also addresses the issues related to the shapes and the sizes of ZnO nanostructures that effect hydrophobic surfaces and studies the method to increase the Water Contact Angle (WCA) on thesynthesized surface to improve self cleaning property.
