Methods for forming an expandable tubular body having a plurality of braided filaments including a first filament including platinum or platinum alloy and a second filament including cobalt-chromium alloy. The methods include applying a first phosphorylcholine material directly on the platinum or platinum alloy of the first filament and applying a silane material on the second filament followed by a second phosphorylcholine material on the silane material on the second filament. The first and second phosphorylcholine materials each define a thickness of less than 100 nanometers.

A fastener sealing material for application to fasteners is formulated from an acrylate present in a concentration of about 90 to about 97 percent by weight of the sealing material and a nanostructured material present in a concentration of about 3 to about 10 percent by weight of the sealing material. The sealant is applied to the fastener as a liquid and is cured using an ultraviolet or LED light source and without the use of heat.

A method of forming a self-cleaning coating on a substrate comprises the step of selecting a substrate, cleaning the substrate, and/or roughening the substrate using an abrasive. In an embodiment, roughening of the substrate create microscopic tortuous grooves. Another embodiment of the method comprises coating the roughened surface with at least one hydrophobic chemical agent. In an exemplary embodiment, the hydrophobic chemical agent covalently binds with the substrate creating nanoscopic grooves. Another embodiment of the present disclosure pertains to an apparatus for depositing a self-cleaning coating on a flat substrate. A further embodiment of the present disclosure pertains to a self-cleaning coating on a substrate comprising a hydrophobic chemical agent covalently bonded to at least one roughened surface of the substrate.

Processes for preparing oleophobic and hydrophobic coatings on a substrate. More particularly, the disclosure relates to omniphobic surface treatment of substrates such as glass, ceramic, glass-ceramic, and the like.

A composition that is easily applied, clear, well-bonded, and superhydrophobic is disclosed. In one aspect, the composition includes a hydrophobic fluorinated solvent, a binder comprising a hydrophobic fluorinated polymer, and hydrophobic fumed silica nanoparticles. Also disclosed is a structure including a substrate coated with the composition, as well as a method for making the composition and a method of coating a substrate with the composition.

A superhydrophobic and self-cleaning surface including a substrate and a superhydrophobic layer. The superhydrophobic layer having a reacted form of octadecyltrichlorosilane. The octadecyltrichlorosilane is disposed on and crosslinked to a surface of the substrate via surface hydroxyl groups. The surface exhibits a rms roughness of 40 nm to 60 nm, a water contact angle of 155 to 180, and a contact angle hysteresis of less than 15. A method of preparing the substrate with a superhydrophobic and self-cleaning surface including treating a substrate with a plasma treatment, contacting the substrate with water or an alcohol to form an hydroxylated substrate, contacting the hydroxylated substrate with a solution of octadecyltrichlorosilane in an alkane solvent at a concentration in the range of 0.05 M to 0.3 M, and drying the solution on to the substrate under ambient air to form the superhydrophobic and self-cleaning surface on the substrate.
