    Abstract: The present disclosure provides an article including an organic layer having a nanostructured first surface including nanofeatures defining nanorecesses and an opposing second surface; and a ceramic layer disposed on the nanostructured first surface of the organic layer and filling at least a portion of the nanorecesses. The ceramic layer has a nanostructured first surface including nanofeatures and an opposing second surface, and the nanostructured first surface of the ceramic layer is interpenetrated with the nanostructured first surface of the organic layer. The present disclosure also provides a method of making the article. The method includes obtaining an organic layer having a nanostructured first surface including nanofeatures defining nanorecesses and an opposing second surface; and filling at least a portion of the nanorecesses of the nanostructured first surface of the organic layer with a ceramic material to form the article. In addition, the present disclosure provides articles including interpenetrating layers having different elastic storage moduli, such as non-metallic layers, and methods of making the articles. The articles can exhibit high abrasion resistance.

    Abstract: Dry erase articles are described comprising a writable surface layer comprising a cured hardcoat composition comprising the reaction product of certain low surface energy compound(s). In one embodiment, the compound(s) comprise a C18-C36 hydrocarbon group and an ethylenically unsaturated group. In another embodiment, a mixture of compounds is utilized, the mixture comprising first compounds comprising a C18-C36 hydrocarbon group and an ethylenically unsaturated group and second compounds comprising a C8-C17 hydrocarbon group and an ethylenically unsaturated group, wherein the first and second compound are present at a weight ratio of 3:2 to 4:1.

    Abstract: Described herein are compositions including a silanol compound that is suitably synthesized, stored, and coated from an aqueous solution. Once coated and cured on a suitable surface, the aqueous silanol compositions result in cleanable and abrasion resistant surfaces, such as dry-erase surfaces that release permanent marker by rubbing with a dry cloth or towel. Also disclosed herein are methods of making the silanol compounds, methods of making cleanable substrates, and cleanable substrates suitably formed using the disclosed methods.
