    Abstract: A display film includes a transparent glass layer having a thickness of 250 micrometers or less, or in a range from 25 to 100 micrometers. A transparent energy dissipation layer is fixed to the transparent glass layer. The transparent energy dissipation layer has a glass transition temperature of 27 degrees Celsius or less, a Tan Delta peak value of 0.5 or greater, or from 1 to 2 and a Young's Modulus (Ε') greater than 0.9MPa over a temperature range of -40 degrees Celsius to 70 degrees Celsius. In a preferred embodiment, the transparent energy dissipation layer comprises a cross-linked polyurethane layer or a cross-linked polyurethane acrylate layer.

    Abstract: A nanocomposite includes at least one polymer and metal oxide nanoparticles dispersed in the at least one polymer. Each polymer can have a number average molecular weight of at least 10000 grams/mole. The at least one polymer includes a first polymer including (meth)acrylic acid monomer units. The metal oxide nanoparticles are surface modified with a carboxylic acid silane surface modifying agent. An aqueous dispersion that can be used to make the nanocomposite and a method of making the nanocomposite is described.

    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: Nanocomposite blends include metal oxide nanoparticles and at least two (meth)acrylic acid polymers where the nanoparticles are surface modified with a carboxylic acid silane and where the (meth)acrylic acid polymers are 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.
