A process of fabricating the waterproof coating may include selecting a substrate, utilizing a sol-gel comprising a silane or silane derivative and metal oxide precursor to coat the substrate, and optionally coating the substrate with a hydrophobic chemical agent and/or other chemical agents to create a surface with nanoscopic or microscopic features. The process may utilize an all solution process or controlled environment for fabricating self-cleaning and waterproof coating that prevent wetting or staining of a substrate, or may utilize a controlled environment.
