    Abstract: 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.

    Abstract translation: 一种流体控制电影提供确实包括流体控制信道沿着通道纵向轴线延伸。 每个流体控制信道的具有表面和被配置为允许在通道中的液体的毛细管运动。 流体控制电影另外包括亲水表面处理共价键合到所述流体控制信道的表面的至少一部分上。 流体控制膜表现出毛细上升百分数至少百分之十的恢复。 典型地，该亲水性表面处理包括从非两性离子磺酸盐，非两性离子羧酸盐，两性离子磺酸盐，羧酸盐两性离子的，两性离子的磷酸盐，两性离子膦酸，和/或两性离子的膦酸根官能团。 如此提供一种用于形成流体控制电影过程。 另外，用于清洁一结构化表面的过程提供了，包括提供具有结构化表面并且共价键合到该结构化表面的至少一部分上的亲水性表面处理，并用材料弄脏结构化表面。 因此，该方法包括通过在wässrige流体在浸没结构化表面，与流体wässrige漂洗所述结构化表面的至少一个移除材料，冷凝成wässrige流体结构表面上，或擦拭用清洁所述结构化表面工具。
