The product which possesses the super hydrophobic nano- texture surface

摘要

The article e.g. ophthalmic lens comprises a network of regularly nanotextured vertical blocks such as parallelepipeds, cylinders, truncated cones or pyramids having a surface fraction (phi ) of 8= phi = 10%, a pitch (p) of 100= p= 250 nm and a height (h) of 150= h= 350 nm. Lateral surfaces of the blocks are inclined to an angle of +- 5[deg] with respect to a vertical axis of the blocks that have rounded tip. The nanostructured surface has an antifouling layer and a roughness (r) of 2.5= r= 3.5, and is partially coated with a hydrophobic material layer having a thickness of 1-5 nm.
