HYBRID ORGANIC-INORGANIC NANOSTRUCTURED UV-CURABLE FORMULATION AND METHOD FOR PREPARATION THEREOF

Torna indietro

Abstract

A nanostructured organic-inorganic hybrid formulation comprising an organic phase based on methacrylic-silane monomers, which is crosslinkable by solar radiations, and an inorganic phase, obtained from an alkoxy-silane precursor, is described. The inorganic phase is composed of continuous silica nanodomains, obtained after hydrolysis and condensation reactions, dispersed within the crosslinked organic phase. The nanostructured organic-inorganic hybrid formulation is crosslinkable by solar radiation and comprises 4-15% by weight of at least one alkoxy-silane compound, 22-90% by weight of trimethoxypropyl silane methacrylate and functionalized poly(dimethylsiloxane)-terminated vinyl, 5-60% by weight of a methacrylic resin and 1-5% by weight of a photoinitiator mixture containing at least one UV photoinitiator and at least one photoinitiator that can be activated by visible light
