摘要： A coating composition includes alkaline mineral particles including an oxide of an alkaline earth metal and an amine-containing polymer. The amine-containing polymer is adsorbed on the alkaline mineral particles. Forming a coating composition includes at least partially coating alkaline mineral particles with an amine-containing polymer and dispersing the alkaline mineral particles in a liquid to yield the coating composition. The alkaline mineral particles include an oxide of an alkaline earth metal.

摘要： The present invention relates to a process for producing a particle dispersion comprising the steps of: a) providing a dispersion consisting of a solvent and solid core particles, b) providing a solution of a soluble, interfacially-active polymer having a molecular weight of more than 5 kDa, c) mixing said dispersion of solid core particles with said polymer solution, d) removing free polymer from the obtained mixture; wherein in step a) the solvent is selected from an organic solvent, a mixture of at least two organic solvents or a mixture of at least one organic solvent with water; wherein in step c), the amount of the soluble, interfacially-active polymer mixed with said dispersion of solid core particles exceeds the amount of polymer required to coat the surface of each of the solid core particles with a monolayer of the polymer; wherein step d) is repeated until the requirement described by the following formula is fulfilled:

(STdisp−18 mN/m)/(STsolv−18 mN/m)>0.90,

with STdisp being the surface tension of the modified particle dispersion in [mN/m] and STsolv being the surface tension of the pure solvent or solvent mixture in [mN/m]; and wherein the solvent or solvent mixture contained in the dispersion of solid core particles is miscible with the solvent or solvent mixture contained in the polymer solution. The present invention also relates to a particle dispersion exhibiting a homogenous drying pattern as well as a film made thereof and the use of the non-aqueous particle dispersion.

摘要： A matter-repellent colloid-infused smooth surface (CISS) device has a solid substrate with a smooth surface where a thin coating of a non-volatile lubricating fluid and a plurality of nanoparticles and/or microparticles reside on the surface. The non-volatile lubricating fluid can be a perfluorinated fluid and the nanoparticles and/or microparticles can be polytetrafluoroethylene (PTFE) to provide a slippery surface to a metal, ceramic, glass, or plastic substrate. As needed, the smooth surface of the substrate can be modified with a silylating agent that is miscible with the lubricating fluid to enhance the stability of the coating smooth surface interface. In this manner, tubes, catheters, vials, bottles, or other devices can be imparted with a slippery surface that repels most gases, liquids, and solids.
