Abstract: This invention relates to polymeric compositions for application onto natural stone in order to provide for long-term chemical, stain, and water resistance, along with antimicrobial properties. Many natural, unsealed stones do not have stain, etch, or water resistance. The described compositions were developed using a technology of chemical grafting that involves the use of prepolymers, monomers, catalysts, graft initiators, wetting agents, antimicrobial agents, and other ingredients. The composition, when thus applied to the stone surface allows it to obtain a graft polymerization, thereby forming a polymer film that is chemically attached to the natural stone, rather than typical physical bonding of other sealer compositions. The natural stones react with a graft initiator in the composition, which creates the reaction sites on the natural stone surface via free radical mechanisms.

Abstract: In this work, a hydrophilic, yet slippery solid surface was developed. Because the surfaces are hydrophilic, there is significant affinity between the surface and contacting water, which results in substantial spreading of the contacting liquids on the surface. Due to their strong affinity, a high solid-liquid adhesion having virtually no mobility of the water on the surface occurs. However, counter-intuitively, the disclosed surfaces are highly slippery such that liquids can slide on the surface while maintaining their hydrophilicity. Demonstrated herein are water droplets that can slide on the surface under its own weight, when the hydrophilic, yet slippery solid surface is slightly tilted (?=3°). This indicates that the disclosed hydrophilic surfaces are slippery to water.
