Abstract: Provided herein are compositions, comprising polysilazane, polysiloxane, and a boron constituent. The compositions may further comprise carbon nanofibers. Also provided is a method for forming the compositions, composites formed from a composition, and a method for forming composites from a composition by mixing the compositions with fibers and curing the composition-fiber mixture.
Abstract: Provided herein are silicon-based compositions, which after curing is a coating composition having strong substrate adhesion and scratch resistance. The compositions are formed from a mixture of constituents comprising: from about 20% to about 90% (w/w) of a first siloxane selected from the group consisting of silsesquioxane, methylmethoxysiloxane, and combinations thereof; and from about 10% to about 80% (w/w) of one or more silicon compounds selected from the group consisting of a second siloxane, silane, and silazane. Optionally, the compositions may comprise from about 0.1% to about 5% (w/w) alkyltitanate.
Abstract: Provided herein is a method for coating a surface. The method comprises providing a towelette moistened with a mixture of constituents to form a silicon-based coating composition comprising silane, siloxane, and an organic solvent. The mixture is transferred from the towelette to form a coating on a surface. The coating is cured ambiently with or without additional heat. Also provided herein is a moistened towelette for coating a surface. The towelette comprises (a) a substrate and (b) a mixture of constituents to form a silicon-based coating composition comprising silane. The mixture is contained within the substrate until applied to a surface, and, after application, the coating of the mixture onto the surface cures ambiently with or without additional heat.
