Abstract: A nanodiamond coating for use on a solar cell, the coating including a nanodiamond material suspended in a liquid, wherein the nanodiamond material has a size range from about 1 nm to about 10 nm. Methods for improving the efficiency of a solar cell are provided, including, mixing a nanodiamond material with a liquid polymer or non-polymer solvent to form a nanodiamond-polymer suspension, forming a coating of the suspension on a top surface of a solar cell, and drying the coating such that a dried nanodiamond-polymer layer remains bonded to the solar cell. Useful nanodiamond coating compositions may include a nanodiamond material, a fluoropolymer, a liquid solvent for the fluoro-polymer and at least one additive selected from the group consisting of dispersing agents, adhesion promoters, and coupling agents. The fluoropolymer may also be used in the form of an aqueous dispersion.

Abstract: The invention relates to low density fluoropolymer foam, and preferably polyvinylidene fluoride (PVDF) foam, such as that made with KYNAR PVDF resins, and articles made of the foam. The foam is produced by adding microspheres containing blowing agents to the polymer and processing it through an extruder. The microspheres consist of a hard shell containing a physical blowing agent. The shell softens at elevated temperatures and allows the expansion of the blowing agent, and microsphere to create larger voids within the polymer matrix. By proper control of the polymer composition, viscosity, processing temperature, blowing agent selection, loading ratio, and finishing conditions, useful articles such as foamed PVDF pipe, tube, profiles, film, wire jacketing and other articles can be produced. The microspheres may be added to the fluoropolymer matrix by several means, including as part of a masterbatch with a compatible polymer carrier.

Abstract: The invention relates to an intertwined multilayer primer/fluoropolymer coating on the glass substrate. The final coating has excellent wet adhesion to glass, good weathering, durability, chalking resistance, chemical resistance, and dirt pickup resistance. The coating is an environmentally friendly aqueous, fluoropolymer coating composition. The coating process involves applying a polyurethane primer to the glass substrate, and partially, but not completely crosslinking this primer coating. An aqueous hydroxyl-functional fluoropolymer coating is then applied to the partially cross-linked primer coating, and the coating allowed to fully cure. The invention also relates to the intertwined multilayer primer/fluoropolymer coating on the glass substrate. The final coating has excellent wet adhesion to glass, good weathering, durability, chalking resistance, chemical resistance, and dirt pickup resistance.
