Abstract
Provided herein is a hierarchical superhydrophobic surface comprising an array of first geometrical features disposed on a substrate comprising a first material and a terminal level disposed on the second features, wherein the terminal level comprises a second material, the second material being different from the first material. The second material has a hydrophilicity different from the hydrophilicity of at least one of 1) the hydrophilicity of the second material and 2) hydrophilicity induced by the hierarchical structure. The present disclosure further includes methods of preparing hierarchical superhydrophobic surfaces and medical devices comprising the hierarchical superhydrophobic surfaces.

A superhydrophobic surface comprising a substrate having superhydrophobicity wherein the superhydrophobicity is generated from a microstructure pattern disposed on the substrate, the microstructure pattern including an array of first geometrical features, the array of first geometrical features having a pitch between adjacent features from 10 to 1000 microns, and a terminal level disposed on the array of first geometrical features, wherein the terminal level is a chemical coating, and wherein the microstructure pattern is configured to generate a Wenzel-Cassie state for adhering the substrate to a target surface.
A superhydrophobic surface comprising a substrate having superhydrophobicity wherein the superhydrophobicity is generated from a microstructure pattern disposed on the substrate, the microstructure pattern including an array of first geometrical features disposed on the substrate, wherein the array of first geometrical features is a two-dimensional sinusoid having a pitch between adjacent features from 10 to 1000 microns, and a terminal level disposed on the first geometrical features, and a terminal level disposed on the array of first geometrical features, wherein the terminal level is a chemical coating, and wherein the microstructure pattern is configured to generate a Wenzel-Cassie state for adhering the substrate to a target surface.
