  • Patent number: 11142867
    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.

  • Patent number: 10927219
    Abstract: The present invention relates to crosslinked silsesquioxane random copolymers absorbing both UVA and UVB although they contain only UVB absorbing chromophores, and methods preparing the same. Crosslinked polysilsesquioxane random copolymers prepared by the method of the present invention have good sensory and are safe as they are not absorbed into human body due to their high molecular weights. These polymers have desirable UV blocking function as they absorb wider range of UV including both UV B (280-320 nm) and UV A (320-400 nm) by excimer or exciplex formation between chromophores. Also, these polymers are useful for UV blocking cosmetics as they do not develop opaque white appearance in high concentration (30%).

  • Patent number: 8859709
    Abstract: A mixture of at least two polyhedral oligomeric silsesquioxane (POSS) compounds is formed in the presence of rhenium on cerium(IV) oxide. The POSS compounds are formed utilizing a method that includes the step of combining (a) a trihalosilane, (b) hydrogen gas, and (c) the rhenium on cerium(IV) oxide, in a reactor at a temperature of from 250° C. to 600° C. to form the mixture. The trihalosilane has the formula RSiX3 wherein R is an alkyl group having from 1 to 4 carbon atoms, an aryl group, and wherein X is a halo atom. This method allows for the efficient, predictable, and accurate production of the POSS compounds with a minimized need for use of expensive separation techniques. In addition, this method produces the POSS compounds in commercially useful quantities as major reaction products thereby avoiding the need to run multiple reactions.
