Abstract
A composite coating having a high refractive index, high Abbe number, low haze and high transmittance, suitable for fabricating nanoscale optical surface features includes a resin with a crosslinked polymer matrix having polymers with repeat units derived from acrylic or methacrylic monomers or oligomers and inorganic nanoparticles disposed within the resin, wherein the composite coating has a refractive index equal to or greater than 1.7 and a glass transition temperature equal to or greater than 60° C.
Claims16
A composite coating comprising:
- a resin including a polymer network, the polymer network including repeat units derived from an acrylic or methacrylic monomer or oligomer;
- and
- inorganic nanoparticles disposed within the resin,
- wherein the composite coating has a refractive index greater than 1.7 and a glass transition temperature greater than 60° C., and
- wherein the polymer network comprises from 25 wt % to 60 wt % repeat units derived from a trifunctional acrylic or methacrylic monomer or oligomer, 40 wt % or more repeat units derived from bifunctional acrylic or methacrylic monomers or oligomers, and, optionally up to 10 wt % repeat units derived from monofunctional monomers or oligomers.
