摘要： The present invention belongs to the membrane separation area, which provides an MXene material based composite nanofiltration membrane and corresponding method. The mentioned membrane is flat membrane, which has supporting layer and functional separation layer and supporting layer is under the functional separation layer. The functional separation layer is a kind of dense ultra-thin layer, no more than 50 μm, prepared with MXene and crosslinking agent. This invention is about a flat composite nanofiltration membrane which has excellent separation performance, thermal resistance and chemical stability because of the novel MXene in the functional separation layer. It can be used in the treatment of the waste water with heavy metal ions, organic solvents or other highly oxidizing solution.

摘要： The present invention relates generally to compositions for use in biological and chemical separations, as well as other applications. More specifically, the present invention relates to hybrid felts fabricated from electrospun nanofibers with high permeance and high capacity. Such hybrid felts utilize derivatized cellulose, and at least one non-cellulose-based polymer that may be removed from the felt by subjecting it to moderately elevated temperatures and/or solvents capable of dissolving the non-cellulose-based polymer to leave behind a porous nanofiber felt having more uniform pore sizes and other enhanced properties when compared to single component nanofiber felts.
