Abstract
Super absorbent material used for drying that integrates super absorbent non-woven fibrous mats with other material, as for example wicking material, are described. The fibrous mats consist of polymeric material embedded with particles of super absorbent polymer. The wicking material may be lightweight knitted fabric that actively absorbs and wicks liquid across the fabric surface. The materials are fabricated as single layer or multiple layers and demonstrate a variety of form factors suitable to the intended use. The super absorbent materials may incorporate additional functionalities, such as antifungal or antibacterial, for biomedical uses.

A method for creating a super absorbing composite material comprising the steps of:
- (a) suspending super absorbing polymer particles within a solution of polymeric material;
- (b) applying said solution to the surface of a wicking material to form a super absorbing composite material with nano- to micro-sized fibers;
- and
- (c) adhering two or more layers of the super absorbing composite material together,
- wherein the polymeric material is polycaprolactone, and wherein a ratio of the polymer particles to polycaprolactone is 4 to 1.
A method for creating a super absorbing composite material, the method comprising:
- suspending a plurality of super absorbing polymer particles in a solution of polymeric material, thereby generating a suspended solution;
- applying the suspended solution to a surface of a wicking material;
- and
- forming the super absorbing polymer particles in the suspended solution into nano-scale to micro-scale fibers directly on the surface, thereby generating a super absorbing composite material,
- wherein the forming step comprises electrospinning.
