Abstract:
1. A three-dimensional film comprising: a first surface with three-dimensional hollow tubular drains extending downward from said first surface and capable of transmitting fluid by gravity; said first surface forming a continuous planar surface wherein any point on said first surface can be accessed from any other point on said first surface without leaving the continuous plane; and a plurality of three-dimensional protrusions originating on said first surface and extending upward from said first surface, each protrusion terminating in an upper surface comprising generally planar land areas, said land areas being generally parallel to and spaced from said first surface, said upper surfaces or said protrusions forming a discontinuous planar surface wherein access to any point on one upper surface of any one protrusion from a point on any other upper surface of any other protrusion cannot be accessed without leaving said discontinuous plane; the land areas on each protrusion having at least two three-dimensional capillary structures comprising hollow tubular structures extending downward from said upper surface toward said first surface, capillary structures being capable of transmitting fluid in contact with said upper surface by capillary action.
