Abstract: A process for forming an abrasion-resistant antistatic layer for an imaging element comprises: adjusting the pH of an aqueous composition of an electronically-conductive polymer to a pH of about 3 to about 10, and combining the pH-adjusted aqueous composition of the electronically-conductive polymer with an aqueous composition at a pH greater than 7 of a polyurethane film-forming binder having a tensile elongation to break of at least 50% and a Young's modulus measured at 2% elongation of at least 50000 psi. The process further comprises applying the resulting coating composition to the imaging element, thereby forming an abrasion-resistant antistatic layer on the element. The antistatic layer coating composition of the present invention can be applied to a wide variety of imaging elements, including, for example, photographic, electrostatographic, photothermographic, migration, electrothermographic, dielectric recording and thermal-dye-transfer imaging elements.

Abstract: An aerogel material with surfaces containing fluorine atoms which exhibits exceptional hydrophobicity, or the ability to repel liquid water. Hydrophobic aerogels are efficient absorbers of solvents from water. Solvents miscible with water are separated from it because the solvents are more volatile than water and they enter the porous aerogel as a vapor across the liquid water/solid interface. Solvents that are immisicble with water are separated from it by selectively wetting the aerogel. The hydrophobic property is achieved by formulating the aerogel using fluorine containing molecules either directly by addition in the sol-gel process, or by treating a standard dried aerogel using the vapor of fluorine containing molecules.

Abstract: A suspension, for use as an oilfield fluid, is composed of at least one ethylene vinyl acetate copolymer, at least one surface active agent other than an ethylene vinyl acetate copolymer and a bipolar solvent. The bipolar organic solvent has a boiling point higher than the melting point of the ethylene vinyl acetate copolymer. The polar and nonpolar groups of the bipolar organic solvent and the ethylene vinyl acetate copolymer(s) form a micellar self-assembly such that the polar groups and nonpolar groups of the ethylene vinyl acetate copolymer(s) are associated with the polar groups and nonpolar groups, respectively, of the bipolar organic solvent. The micellar self-assembly serves as a vehicle for the incorporation of the surface active agent(s) into a single multi-component blend. Suitable surface active agents include corrosion inhibitors, scale preventatives, demulfisying agents, paraffin inhibitors, gas hydrate inhibitors, flocculanting agents as well as asphaltene dispersants. The suspensions are prepared by heating and mixing a mixture comprising the surface active agents, ethylene vinyl acetate copolymer(s), and bipolar organic solvent to a temperature sufficient to solvate the ethylene vinyl acetate copolymer(s), preferably from about 280 to about 375null F. The product is then air cooled such that the ethylene vinyl acetate copolymer(s) are excluded to form the suspension.
