Abstract
A method of treating a polycarbonate glass surface, such as a bisphenol A polycarbonate, whereby the glass surface is immersed in a liquid phase polar aprotic solvent, such as dichloromethane, and exposed to a vapor phase polar aprotic solvent, such as acetone thus obtaining a textured glass surface with a hierarchical patterned nanoporous structure wherein the textured glass surface has a higher surface hydrophobicity and a marginally reduced optical light transmittance relative to the polycarbonate glass surface prior to the immersion, the exposure, or both.
