Publication number: 20170335508Abstract: A process of fabricating the composition 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 composition coating that prevent wetting or staining of a substrate. The composition coatings for treating textile materials improve soil-resistance and stain-resistance of the textile materials. The composition coatings and their use for treating textile materials can also impart water repellency, oil repellency, ease of cleaning stains and removing particulates. In addition, the composite solution may impart additional properties such as physical strength to the textile whilst retaining the original appearance.Type: ApplicationFiled: November 12, 2015Publication date: November 23, 2017Inventors: Seamus Curran, Kang-Shyang Liao, Nigel Alley, Amrita Haldar, Alexander Wang

Publication number: 20170313888Abstract: A process for manufacturing the composition coating may include selecting a wood or masonry material substrate and utilizing a sol-gel comprising a silane or silane derivative and metal oxide precursor to coat the substrate. The process may utilize an all solution process or controlled environment for manufacturing a composition coating that prevent wetting and/or staining of a substrate. The composition coatings for treating wood or masonry materials improves weather-resistance, microbial resistance, stain-resistance and fungal-resistance of the materials. The reduced permeability of the resulting masonry materials can also delay or inhibit degradation caused by permeation of ions such as chlorides and sulfates. In addition, a stain comprising the composite solution and pigments may impart additional property to wood or masonry materials whilst retaining or improving the original appearance, particularly for the visibility and contrast of the wood grain as seen after the application of the coating.Type: ApplicationFiled: November 12, 2015Publication date: November 2, 2017Inventors: Seamus Curran, Kang-Shyang Liao, Nigel Alley, Amrita Haldar, Alexander Wang

Patent number: 9790336Abstract: A composition and method for fabricating graphitic nanocomposites in solid state matrices is presented. The process for fabricating graphitic nanocomposites in solid state matrices may include selecting one or a mixture of specific graphitic nanomaterials. The graphitic nanomaterial(s) may be functionalizing with a moiety similar to the building blocks of the solid state matrices. The functionalized graphitic nanomaterials are mixed with the building blocks of the solid state matrices. The mixture may be cured, which causes in situ formation of the sol-gel solid state matrices that entraps and/or covalently links with the graphitic nanomaterials during the network growing process. This process allows the nanomaterials to be introduced into the matrices homogeneously without forming large aggregations.Type: GrantFiled: January 30, 2015Date of Patent: October 17, 2017Assignee: UNIVERSITY OF HOUSTON SYSTEMInventors: Seamus Curran, Kang-Shyang Liao, Alexander Wang
