The present invention relates generally to compositions for use in biological and chemical separations and other applications. More particularly, the present invention relates to a hybrid felt made from electrospun nanofibers with high permeability and high capacity. Such hybrid felts are at least one non-cellulosic polymer that can be removed from the felt by subjecting it to derivatized cellulose and a mildly elevated temperature and / or solvent capable of dissolving the non-cellulosic polymer. To leave behind a porous nanofiber felt having a uniform pore size and other improved properties compared to a single component nanofiber felt. [Selection] Figure 1 |
