Durable, transparent, inorganic-organic hybrid hydrophobic coating materials for glass, metal or plastic substrates are provided. The coating materials are generally an acid catalyzed condensation reaction product comprised of an organic polymeric silane (e.g., a polyol functionalized with a silane through a urethane linkage or a polyamine functionalized with a silane through a urea linkage, such as isocyanatopropyltrimethoxysilane or isocyanatopropyltriethoxysilane), an inorganic metal alkoxide (e.g., silicon alkoxides such as tetraethoxysilane or tetramethoxysilane) and a fluorinated silane (e.g., (3,3,3-trifluoropropyl)trimethoxysilane or nonafluorohexyltrimethoxysilane).

Coating compositions which include a blend of a fluorochemical and a particulate additive comprising a bimodal size distribution of inorganic nanoparticles are provided. The bimodal distribution of inorganic nanoparticles may include a quantity of smaller nanoparticles having an average size distribution of between about 1 to about 15 nm, and a quantity of larger nanoparticles having an average size distribution of between about 40 to about 500 nm. The smaller and larger nanoparticles may be present in a ratio of the smaller sized particles to the larger sized particles of at least 1.2, with the total amount of nanoparticles being present in an amount of between about 0.1 to about 10 wt. % based on total composition weight.

The present invention is directed toward a self-decontaminating surface coating, which when cured has a partially hydrophobic surface. The coating comprises a polymeric coating resin which, when cured, is hydrophilic. The coating also comprises a biocide, a germinating agent, and a hydrophobic micro/nano particulate material. The coating is suitable for application to ceramics, metals, and polymer substrates. Articles coated with the coating of the present invention are resistant to spores.

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.

Synthetic textile articles (e.g., filaments, fibers, yarns, fabrics and the like) and processes of making the same are provided which include flame-retardant SAP particles. The SAP particles are most preferably hydrated with an aqueous flame-retardant solution. In this regard, the flame-retardant solution may consist essentially of water alone or a water solution containing one or more water soluble inorganic flame retardants. When SAP particles are hydrated with an aqueous inorganic flame retardant solution, the SAP particles may thereafter be dried to remove substantially the water component. In such a manner, the inorganic flame retardant will remain as a dried residue physically entrained within the SAP particles. As such, the SAP particles serve as a physical matrix in which the inorganic flame retardant is homogenously dispersed. The SAP particles may then be chemically or physically affixed to the textile article in an amount sufficient to render the article flame-retardant.

The present invention is directed toward a tunable dielectric device comprising: a substrate and an endohedral fullerene encapsulating trimetallic nitride template compound disposed on the substrate. The endohedral fullerene encapsulating trimetallic nitride template compound has a dipole moment that is oriented when a voltage of less than about 5 volts is applied thereto causing a change in the orientation of the dipole moment of the compound. The physical dimension of the compound is essentially unchanged.
