WETTABILITY BEHAVIOR OF SUPERHYDROPHOBIC SILICONE RUBBER COATINGS AT SUPERCOOLED TEMPERATURES

摘要：

A superhydrophobic surface was prepared by anodization of aluminum substrates in phosphoric acid followed by RTV silicone rubber coating. Study of the surface wetting properties showed a high static contact angle, up to 160 ° for the treated surfaces at room temperature. Scanning electron microscopy image analysis showed that birds nest and beehive structures had formed on the anodized surfaces at 50 V and 80 V. The results showed that higher anodizing voltage leads to larger pore sizes. The freezing behaviour of 4-uL water droplets was investigated on nanostructured aluminum surfaces and compared with that on flat surfaces and hydrophobic aluminum surface.
