Hybrid felt of electrospun nanofibers

摘要

To provide a composition used for biological and chemical separation and used in other applications as a whole, and more specifically, to provide a hybrid felt made of electro-spun nanofibers having high transmittance and high capacity.MEANS FOR SOLVING THE PROBLEM: Such a hybrid felt uses a derivatized cellulose and at least one non-cellulosic polymer that can be removed from the felt by being subjected to a moderately elevated temperature and/or a solvent capable of dissolving the non-cellulosic polymer and leaves a porous nanofiber felt having a uniform pore diameter and other improved properties as compared to a single-component nanofiber felt.SELECTED DRAWING: Figure 1
