Abstract: A method of preparing an antimicrobial coating comprises coating a surface with an aqueous mixture of 3-(trihydroxysilyl)propyl dimethyloctadecyl ammonium chloride, 3-chloropropyltrimethoxysilane, and triethanolamine and then coating the surface with an aqueous titanyl sol-gel solution comprising an aqueous mixture of peroxotitanium acid and peroxo-modified anatase sol overtop of the silane to form the antimicrobial coating. The antimicrobial coating exhibits residual antimicrobial efficacy against E. coli and S. epidermidis after water rinsing or after abrasion. The use of 3-chloropropyltrimethoxysilane was found to improve storage stability of the quaternary silane composition and the durability of the antimicrobial coating.

Abstract: A superhydrophobic ceramic coating that is transparent and durable includes a dispersion of a multiplicity of silica nanoparticles stacked to form a topography that is rough that is infused with and conformally coated with a sol-gel glass matrix that has a fluoroalkyl silane or an alkyl silane monolayer on the surface of the coating.

Abstract: A self-healing composite material includes a polymer matrix, microcapsules filled with a ring-opening metathesis-active monomer (e.g., norbornene, norbornene derivatives such as ethylidene norbornene, or cyclooctadiene), and polymeric particles comprised of a polymer that is soluble in the monomer with which the microcapsules are filled and having catalytic endgroups derived from an olefin metathesis catalyst, such as a Grubbs'-type catalyst.

The polymer having catalytic endgroups may then be processed via a grinding operation, for example, to prepare the small polymeric particles. In other embodiments, the polymeric particles are synthesized directly as microparticles (e.g., microspheres, granules, beads, etc.
