  • Publication number: 20230390971
    Abstract: Transparent articles and methods of producing transparent articles are provided. The transparent article includes hydrophobic nanoparticles dispersed within poly(methyl methacrylate). The method of producing transparent articles includes pouring a transparent article precursor into a mold, the transparent article precursor comprising nanoparticles, a solvent, and a polymer, and the mold comprising a flat surface. The method also includes placing the mold into a container having an adjustable opening and allowing the solvent to evaporate from the transparent article precursor, thereby forming the transparent article over the flat surface of the mold. The method further includes flattening the transparent article, in which flattening the transparent article includes positioning a flat article on a first side of the transparent article, and compressing the transparent article between the flat surface and the flat article.

  • Publication number: 20230203320
    Abstract: According to one or more embodiments, an antifouling material may be produced by forming a nanostructured mold, where a liquid mold precursor is contacted with a textured surface of a nanostructured template, the liquid mold precursor is solidified to the nanostructured template, and the formed nanostructured mold is removed from the nanostructured template. The antifouling material may be formed by contacting a liquid precursor mixture with a textured surface of the nanostructured mold, solidifying the liquid precursor mixture onto the nanostructured mold, and removing the formed antifouling material from the nanostructured mold. The antifouling material may include a nanostructured surface and may further include a toxin.
