Abstract: The present invention relates to a nanofilter formed by using a porous ultrafiltration membrane as a precursor, and carefully controlling reaction conditions so as to maintain sufficient hydrophilic nature of the membrane while causing the pore structure to close to a nanofilter range (less than 400 Daltons). This produces a solvent stable cellulose nanofiltration membrane capable of operating at satisfactory flux in aqueous solutions, and being low binding to organic biomaterials.

Abstract translation: 本发明涉及通过使用多孔超滤膜作为前体形成的纳米过滤器，并仔细控制反应条件，以便在使孔结构接近纳米过滤范围（小于400道尔顿）的同时保持膜的充分亲水性， 。 这产生了能够在水溶液中以令人满意的助熔剂操作并且与有机生物材料结合低的溶剂稳定的纤维素纳米过滤膜。
