Preparation and basic property of superhydrophobic silicone rubber surfaces

In the outdoor insulating, the most important property of silicone rubber is its hydrophobicity. In recent research of interface and adhesion, wettability control has been widely investigated for technological applications such as self-cleaning surfaces by modifying both the geometric structure and the chemical composition of the surfaces. Water droplets on lotus-leaf-like superhydrophobic surface can pick up dirt particles and remove contamination. This property is an idea state for outdoor insulating material. In this article, we give a way to make a surface modification of silicone rubber. By using of high power picosecond laser in cooperated with a high speed scanning mirror, micro pit with nano substructures can be fabricated on mold steel. This kind of mold is used in the directly…
