Abstract:
Capillary channel structures having one or more intrastructure capillary channels, said structures comprising a polymer composition, wherein: said structures have a capillary channel base, and at least two polymeric capillary channel walls extending from said base along the length of said base in the axial direction for at least about 0. 2 cm, said walls having a base end and a distal end, wherein said base and walls form said capillary channels; and said structures have a Specific Capillary Volume of at least about 1. 2 cc/g, a Specific Capillary Surface Area of at least about 500 cm. sup. 2 /g, and a Compressive Strength (Dry) of at least about 13,800 dynes/cm. sup. 2. The structures can be in the form of fibers or sheets. The fibers have a Specific Capillary Volume of at least about 2. 0 cc/g and a Specific Capillary Surface Area of at least about 2000 cm. sup. 2 /g.
