Abstract

Chromatography media including a high surface area thermoplastic porous nanofiber and an ion-exchange ligand functionality on the surface of the fiber. The porous nanofibers display a convoluted structure that is comprised of discrete bundles of highly entangled nanofibrils that may be fibrillated or ridged. The porous fibers can be prepared through the extraction of a dissolvable mineral or polymeric porogen that is embedded into the fiber during its manufacture in a melt extrusion process.
