Transparent Nanoporous Glass-Polymer Composite for U.S. Army Applications
Abstract
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.
