Abstract: Nanocomposites include metal oxide nanoparticles and (meth)acrylic acid polymers where the nanoparticles are surface modified with a carboxylic acid silane and where the (meth)acrylic acid polymer is at least partially neutralized. The compositions are transparent, with high transmission and low haze up to very high nanoparticle loading. The compositions also exhibit improved mechanical properties of impact resistance and tensile modulus.

Abstract: A nanocomposite is provided including layered nanoparticles and a dispersant dispersed in a curable resin, where the nanocomposite contains less than 2% by weight solvent. A composite is also provided including from about 1 to 70 weight percent of layered nanoparticles, and a dispersant, dispersed in a cured resin, and a filler embedded in the cured resin. Further, a method of preparing a nanoparticle-containing curable resin system is provided including mixing from 1 to 70 weight percent of aggregated layered nanoparticles with a curable resin and a dispersant to form a mixture. The mixture contains less than 2% by weight solvent. The method also includes milling the mixture in an immersion mill containing milling media to form a milled resin system including layered nanoparticles dispersed in the curable resin.

Abstract: A nanocomposite is provided including spherical pyrogenic silica nanoparticles dispersed in a curable resin or a curing agent. The nanocomposite contains less than 2% by weight solvent and less than 0.5% by weight dispersant based on the nanoparticle weight. A composite is also provided including from about 4 to 70 weight percent of spherical pyrogenic silica nanoparticles dispersed in a cured resin, and a filler embedded in the cured resin. Optionally, the composite further contains a curing agent. Further, a method of preparing a nanoparticle-containing curable resin system is provided including mixing from 10 to 70 weight percent of aggregated spherical pyrogenic silica nanoparticles with a curable resin to form a mixture. The mixture contains less than 2% by weight solvent and less than 0.5% by weight dispersant based on the nanoparticle weight. The method also includes milling the mixture in an immersion mill containing milling media to form a milled resin system including silica nanoparticles dispersed in the curable resin.
