This report explores the manufacturing of a novel transparent polymer-glass composite. The material is created by infiltrating nanoporous glass Vycor, Corning Inc. with different polymers. The Vycor pores 4-6 nm are much smaller than the wavelength of light thus, refractive index matching with the polymer is not necessary for transparency. Close to 90 of the pore volume can be filled by soaking the porous glass in methyl methacrylate and polymerizing in situ. The resulting composite is 95 transparent with excellent clarity, extremely low haze, and an elastic modulus that is well predicted by micromechanics.
