Claim of US Patent No. 10,398,041

1. A method of making a hydrophobic surface for an object, comprising:applying a hydrophobic coating to an original surface of the object;
forming a microstructure on the original surface of the object; andobtaining the hydrophobic surface with the microstructure submerged by the hydrophobic coating, wherein forming the microstructures on the original surface of the object comprises: embedding the microstructure into the hydrophobic coating after the hydrophobic coating is applied to the original surface, to enable the hydrophobic coating to submerge the microstructure;wherein the microstructure is a rough structure including micro-sized portions, and the microstructure has greater hardness than the hydrophobic coating.
