    摘要： A fluid control film is provided that includes fluid control channels extending along a channel longitudinal axis. Each of the fluid control channels has a surface and is configured to allow capillary movement of liquid in the channels. The fluid control film further includes a hydrophilic surface treatment covalently bonded to at least a portion of the surface of the fluid control channels. The fluid control film exhibits a capillary rise percent recovery of at least ten percent. Typically, the hydrophilic surface treatment includes functional groups selected from a non-zwitterionic sulfonate, a non-zwitterionic carboxylate, a zwitterionic sulfonate, a zwitterionic carboxylate, a zwitterionic phosphate, a zwitterionic phosphonic acid, and/or a zwitterionic phosphonate. A process for forming a fluid control film is also provided. Further, a process for cleaning a structured surface is provided, including providing a structured surface and a hydrophilic surface treatment covalently bonded to at least a portion of the structured surface, and soiling the structured surface with a material. The process also includes removing the material by at least one of submerging the structured surface in an aqueous fluid, rinsing the structured surface with an aqueous fluid, condensing an aqueous fluid on the structure surface, or wiping the structured surface with a cleaning implement.

    摘要： A method of making surface-functionalized transition metal oxide nanoparticles comprises: providing a sol comprising transition metal oxide nanoparticles dispersed in an aqueous liquid medium having a pH of less than or equal to 3.5, combining the sol with an extractant composition comprising at least one carboxylic acid and at least one organic amine, and a water-immiscible organic solvent, and separating at least a portion of the organic phase from the aqueous phase and then at least partially removing the water-immiscible organic solvent. The carboxylic acid has from 6 to 30 atoms. The organic amine is represented by the formula R2R3NH, wherein R2 is a hydrocarbyl group having from 6 to 30 carbon atoms, and R3 is H or an alkyl group having from 1 to 4 carbon atoms. The at least one organic amine is present in an amount sufficient raise the pH to at least 5, thereby forming discrete separable aqueous and organic phases. A surface-modified nanoparticle composition, a curable composition and an article comprising the same are also disclosed.
