The present invention relates to textile articles and clothing such as outdoor garments, indoor garments, and commercial protective wear exposed to contact mixtures of water and oil, swimwear and winter wear exposed to mixtures of water and air. At least part of these textile articles possess a surface provided with at least one of 1) a high surface area, 2) hierarchical pattern, 3) contact angles such that hydrophilic portion of a contact mixture possesses a high contact angle and the hydrophobic portion of a contact mixture possesses a low contact angle, and 4) hysteresis angle greater than 5 degrees. Hydrophobic/Hydrophilic contact mixtures of the present invention can be surfaces where water and or ice are present in combination with oil and or air. The textile articles of the present invention resist slippage on surfaces possessing hydrophobic/hydrophilic contact mixtures.
An article comprising a microstructured surface capable of forming an adhesion to a contact surface wherein the microstructured surface comprises a hierarchical pattern including a plurality of first microfeatures, a plurality of second microfeatures disposed about the plurality of first microfeatures, and a plurality of third microfeatures disposed about the plurality of second microfeatures, wherein the hierarchical pattern is configured to develop a hydrophobic region associated with one of the first, second, or third plurality of microfeatures, and a hydrophilic region associated with at least one of the microfeatures that does not develop the hydrophobic region such that the adhesion of the microstructured surface occurs when shear stress exceeds a normal force and wherein the microstructured surface comprises a hysteresis angle greater than 5 degrees.
