Abstract: Fluoroalkylsilane-treated metal oxide particles and a fluoroelastomeric binder are dispersed in a fluorinated solvent with a low boiling point and applied to a substrate via spray deposition. The spray deposition process rapidly produces a conformal coating that features low surface energy and surface topography with a large range of characteristic length scales and re-entrant curvature, thereby imparting superoleophobicity. The degree of superoleophobicity is readily adjusted by means of altering the ratio of particles to binder. The choice of particle and binder result in coatings with thermal stability for thousands of hours at temperatures up to 200 degrees Celsius as well as desirable mechanical characteristics.

Abstract: This invention discloses a method for preparing rubber compositions that exhibit unique combinations of properties that are desirable for tire tread applications for enhanced snow/ice and wet traction, low rolling resistance and increased treadwear performance in comparison with conventional silica compounds. Specifically, a high reactively silane coupling agent, such as a mercaptosilane, is used in combination with a silane coupling typically used for silica tread compounds such as bis(triethoxylsilylpropyl)disulfide to treat silica pellets in a hydrocarbon solvent at elevated temperatures. The treated silica is then blended with solution elastomer cement in a hydrocarbon solvent. The deposited reactive silanes partially react with the elastomer molecules forming a layer of polymer grafted on the silica surfaced. This structure significantly improves the silica retention during the steam stripping operation. Almost 100% (99+%) silica retention has been achieved by this invention.
