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 (E′) greater than 0.9 MPa 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 display film includes a transparent polymeric substrate layer having a 0.2% offset yield stress greater than 110 MPa and a transparent aliphatic cross-linked polyurethane layer having a thickness of 100 micrometers or less disposed on the transparent polymeric substrate layer. The transparent aliphatic cross-linked polyurethane layer has a glass transition temperature in a range from 11 to 27 degrees Celsius and a Tan Delta peak value in a range from 0.5 to 2.5. The display film has a haze value of 2% or less.

Abstract: A nanocomposite is provided including nonspherical silica nanoparticles dispersed in a curable resin or a curing agent, where the nanocomposite contains less than 2% by weight solvent. A composite is also provided including from about 4 to 70 weight percent of nonspherical silica nanoparticles 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 10 to 70 weight percent of aggregated silica nanoparticles with a curable resin and optionally a dispersant, a catalyst, a diluent, a surface treatment agent, and/or a curing agent, 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 nonspherical silica 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.

Abstract: A hardcoat composition includes one or more multifunctional (meth)acrylate monomers, and a nanoparticle mixture dispersed within the one or more multifunctional (meth)acrylate monomers. The nanoparticle mixture includes a first population of reactive nanoparticles. The first population of reactive nanoparticles have an average particle diameter in a range from 5 nm to 60 nm, and a second population of non-reactive nanoparticles. The second population of non-reactive nanoparticles have an average particle diameter in a range from 5 nm to 60 mn.

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.
