Abstract: A process of fabricating the waterproof coating may include selecting a textile material 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 a fluorine-free waterproof coating that prevent wetting or staining of a substrate, or may utilize a controlled environment. The composition coatings for treating textile materials improve soil-resistance and stain-resistance of the textile materials while the compositions contain no fluorine-based chemicals. In addition, the composite solution may impart additional properties such as physical strength to the textile whilst retaining the original appearance.

Abstract: A system and method for depositing a coating may comprise a coating chemical reactor, surface activation component, and a deposition component. A target surface may be prepared for deposition with the surface activation component. The coating chemical reactor may comprise a coating chemical dispenser and a coating chemical verifier that prepares the coating chemical for deposition. The coating chemical verifier may utilize an optical excitation source and at least one optical detector, wherein chemical substances are identified by unique signatures composed of binary code. The coating chemical may be received by the deposition component to depositing the coating chemical on the target surface.

Abstract: Compositions and methods for improved materials and material laminates with graphitic or inorganic/organic nanomaterials are presented. Graphitic or inorganic/organic nanomaterials, such as carbon nanotubes, carbon nanofibers, graphenes or graphene oxides, are introduced into an aqueous composition as fillers to provide a graphitic or inorganic/organic nanocomposite. Such composition may be used as laminates to improve adhesion between a film and a layer of material or between layers of materials and to increase not only strength properties, but also to provide other desired properties such as electronic properties, UV absorbing/blocking, optical-limiting, anti-reflective, fire-retardant, conducting, anti-microbial properties or pigmentation to say material. By tailoring the composite formulations with multiple graphitic or organic/inorganic nanomaterials, the resulting materials laminates become multifunctional and can be used for a variety of applications.
