Advantageous embodiments of the hybrid sol-gel coating and of the method of preparation, respectively, are provided in the dependent claims Preferably, the present invention provides a highly densified hybrid sol-gel coating based on the interconnectivity of two hybrid networks formed from a methacrylate silane and a transition metal complex.

Abstract: A thermophotovoltaic (TPV) system, comprises a substrate, an emitter material adhered to the substrate, and a thermophotovoltaic (TPV) cell. The emitter material is a typically a metal oxide doped nickel oxide sol-gel material, in which the metal is magnesium or zirconium, and in which the sol-gel material comprises 97-99 mol % metal oxide, and about 1-3 mol % nickel oxide dopant. Providing an emitter material as a sol-gel allows the material to be coated on to surfaces providing better adherence to the surface, and also provides excellent heat stability. A sol-gel material is also described.

Abstract: A sol-gel coating composition comprising a hydrolysed organosilane, an organometallic precursor and a corrosion inhibitor, wherein the corrosion inhibitor is a chelator for the organometallic precursor. The corrosion inhibitor and the organometallic precursor may form a nanoparticulate complex. The coating composition may comprise one or more additive selected from: an antimicrobial additive, a hardener, a water repelling additive, a dye, a scratch resistant additive and a flexibility enhancing additive. A process for preparing a sol gel coating composition is also described, the process comprising the steps of: hydrolysing an organosilane in the presence of a catalyst; chelating an organometallic precursor; mixing the hydrolysed silane and the chelated organometallic precursor; and hydrolysing the organosilane-organometallic precursor mixture.
