    Abstract: A method for forming a metallic nanoparticle and semiconductor coated surface, such as the surface of a fiber or other material is provided. The method can include the steps of coating at least one surface of a material, for example a textile material, with a semiconducting layer, and providing metallic nanoparticles on the semiconducting layer. The steps for coating a surface of a material with a semiconducting layer can include forming a titanium dioxide film on the surface of the textile or other material. The steps for depositing and/or providing metallic nanoparticles on the semiconducting layer can include immersing a surface having a semiconductor layer into a metallic nanoparticle precursor solution, drying the semiconductor layer, and exposing the semiconductor layer on the surface to UV radiation. The metallic nanoparticles can include gold and/or silver nanoparticles. Also disclosed are surface treated materials having a semiconductor layer thereon, wherein the semiconductor layer is treated to include metallic nanoparticles. The surface treated materials may comprise surfaces of a textile material, such as fibers. The surface treated materials are anti-microbial and resistant to peeling, as well as non-toxic to biological surfaces, such as skin. Treated fiber materials may be used in garments, masks, and other products that contact the skin, that are free of toxic/rash side effects.

    Abstract: The present invention provides aerogel materials based on imidazoles and polyimidazoles. The polyimidazole based aerogel materials can be thermally stable up to 500° C. or more, and can be carbonized to produce a carbon aerogel having a char yield of 60% or more, specifically 70% or more. The present invention also provides methods of producing polyimidazole based aerogel materials by reacting at least one monomer in a suitable solvent to form a polybenzimidazole gel precursor solution, casting the polybenzimidazole gel precursor solution into a fiber reinforcement phase, allowing the at least one gel precursor in the precursor solution to transition into a gel material, and drying the gel materials to remove at least a portion of the solvent, to obtain an polybenzimidazole-based aerogel material.

    Abstract: A method for manufacturing water repellent fabrics by use of metal oxide colloidal solutions is disclosed. The fabric is dipped and processed in metal oxide colloidal solution and then is through heat treatment so as to make the fabrics with surface roughness on nanometer scale. Then through water repellent treatment, the fabrics has surface with water contact angle above 150°. The water droplets rolls off on fabrics surface and carry away contaminants so as to achieve self-cleaning effect.

    Abstract: A method is proposed for the application of a finishing layer to a textile support material. By means of the novel method, a water repellent or oil repellent layer, a so-called finishing layer, is applied to a textile support material selected from the group of fibers, tissues, and fabrics. The water repellent or oil repellent finishing layer comprises at least two water repellent or oil repellent components wherein a first component comprises one or more dispersants and a second component comprises one or more dispersed phases or colloids, and wherein the dispersant and the dispersed phase are present in the gel state. The colloids of the dispersed phase are distributed in the dispersant in an anisotropic manner so that the colloids are concentrated in the region of the upper surface of the finishing layer forming an interface between the finishing layer an the surrounding atmosphere. In a first step of the finishing method the dispersion in a sol state is applied to the support material, and in a subsequent step is transformed into the gel state. The components of the dispersion have an inherent capability to self-organize with is utilized to achieve an anisotropic distribution. Furthermore, textile articles are proposed having the novel water repellent or oil repellent finishing layer which are equal on a high level or even superior with respect to their functional properties to products prepared according to known finishing methods and at the same time allow a complete or partial substitution of the health and environmentally hazardous standard chemicals employed nowadays by novel compounds which have not been used to date.
