Superhydrophobic coating

Invented by: Mariusz Paszkowski
Krakow, PL

Originally Assigned to: CNT Spolka Z O.O.
Krakow, PL
[Now assigned to . . .]

Issued:2006-02-07
Filed:2002-10-29
Application No:10493054
Examined by:Sotelo; Jesus D.

This invention solves the problem of reducing the fluid friction resistance accompanying relative movement of surfaces of a solid and a liquid. A superhydrophobic coating acting as a substrate for a gaseous lubricant of very low viscosity, reducing the fluid skin friction, has a hierarchic fracal structural of the surface wherein the forms of the first hierarchic level (2, 3, 9) are located at the coating's substrate, and the forms of each successive hierarchic level (22, 33, 99) are located on the surface of the previous hierarchic level and the forms of individual higher hierarchic levels reiterate the forms of the lower hierarchic levels. Forms of at least two hierarchic levels of rows (2, 22) and ridges (3, 33, 99) occur in the coating and, also, the surface has anisotropic geometry, maximally developed fractally in the direction transverse to the direction of flow and maximally smooth in the direction of flow and, also, has channels located in the coating's substrate to ensure gas flow.
