Additive particles may be employed in sufficient amounts to impart superhydrophobicity to a coating system in which the additive particles are incorporated. The additive particles include carrier microparticles and a dense plurality of nanoparticles adhered to the surfaces of the carrier microparticles (e.g., preferably by electrostatic deposition or covalent bonding). The additive particles are advantageously incorporated into a coating material (e.g., a polymeric material) in amounts sufficient to render a substrate surface superhydrophobic when coated with the coating material. The substrate may be rigid (e.g., glass, ceramic or metal) or flexible (e.g., a polymeric film or sheet or a fabric). In some preferred embodiments, both the microparticle and nanoparticles are formed of silica and are surface treated with a hydrophobic treatment so as to impart superhydrophobic properties thereto. Especially preferred are particles treated with silicone fluid comprised of a polysiloxane and / or a perfluoro silane having between 1 and 40 carbon atoms.

A topical insect repellent with extended duration of protection was obtained from mixtures of molecules based on two or more volatile repellent organic molecular species occurring naturally on the human skin surface. The novel repellent comprises mixtures of lower, intermediate, and higher volatility organic molecules. Active ingredients for formulations are obtained from homologous series of carboxylic acids, alcohols, ketones, and lactones which span a similar range of volatility and which occur naturally on the skin surface. Volatile silicone fluid imparts mildness and water repellency to the repellent formulations. The new natural repellent exhibits the longevity and repellency that is comparable to N,N-diethyl-m-toluamide (DEET), a synthetic compound employed in almost all commercial formulations, but the inventive natural repellent is more acceptable than DEET, which has an unpleasant odor and imparts a greasy feel to the skin. The inventive insect repellent, formulated in a volatile silicone fluid, was shown to repel and incapacitate stable flies. This finding demonstrated that repellency was not limited to mosquitoes, but extends to other biting flies or insects, thus demonstrating the utility of the novel insect repellent for protecting pets and livestock as well as humans.
