Abrasion resistant superhydrophobic coatings
Improved superhydrophobic and/or super-oleophobic multi-layer coating compositions or treatments having increased durability and abrasion resistance, the compositions having a bottom layer with solid particles possessing high abrasion resistance and a top layer with particles imparting the superhydrophobic and/or super-oleophobic properties, wherein the bottom layer particles are significantly larger and significantly more abrasion-resistant than the top layer particles, such that portions of the bottom layer particles are exposed on the surface when part of the top layer is abraded, thereby creating an effective contact surface that significantly reduces further abrasion of the top layer without significantly reducing the superhydrophobic and/or super-oleophobic properties.. .

Superhydrophobic aerogel that does not require per-fluoro compounds or contain any fluorine
Provided are superhydrophobic coatings, devices and articles including superhydrophobic coatings, and methods for preparing the superhydrophobic coatings. The exemplary superhydrophobic device can include a substrate component and one or more superhydrophobic coatings disposed over the substrate component, wherein at least one of the one or more superhydrophobic coatings has a water contact angle of at least about 150° and a contact angle hysteresis of less than about 1°.

Coated medical device
A method and apparatus for inserting a medical device such as a cannula tip within a peripheral vein of a human body wherein the medical device includes a micro- or nano-structured superhydrophilic basecoat and a liquid topcoat, together comprising a superhydrophobic coating, which inhibit occlusion and/or catheter related bloodstream infection.. .

Process for preparing an optically clear superhydrophobic coating solution
Optically clear hydrophobic and superhydrophobic coatings and solutions and methods for preparing them. Branched polysilicate structures having surface hydroxyl groups are formed by at least partially hydrolyzing an alkoxy silane precursor via water and an acid catalyst in a solvent, and catalyzing the hydrolysis product with a base to form a gel.
