Porous polymeric fibers having nanoscale morphologies
Owing to their high surface/volume ratio, nanoscale materials have special physical and chemical properties. The processes for producing porous nano- and mesoscale fibers known so far require plural steps and are time and cost intensive.
The novel manufacturing process according to the present invention allows for the simpler, faster and less expensive manufacturing of fibers with a very large surface area. All known polymers and polymer mixtures can be processed into porous hollow fibers with the novel manufacturing procedure. The fiber material may be processed into wovens, drawn-loop knits, and shaped or structured pressed stock. Likewise, it is possible to modify or functionalize the surface of the fiber material.
