    摘要： A porous synthetic membrane suitable for conducting macromolecular fluid separations ( e . g ., protein filtration) is described. The ultraporous membrane comprises a surface-charge layer of crosslinked polymer, the crosslinked polymer being formed from a cellulosic polymer and a crosslinking reagent. The cellulosic polymer has substantial crosslinkable hydroxyl moiety content. The crosslinking reagent is a bi- or multi-functional epoxide capable of reacting with and binding to the cellulosic polymer's hydroxyl moieties and has the formula X(CH 2 )nY, wherein: n is an integer from 1 to 5; X is H 2 COCH or H 2 COCHCH 2 O; and Y is a halogen, H 2 COCH, or H 2 COCHCH 2 O. The porous synthetic membrane has good durability and good protein binding characteristics. Surface charge is provided by covalently binding a charged moiety onto a surface of said layer of crosslinked polymer.

    摘要： 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 400Daltons), This produces a solvent stable cellulose nanofiltration membrane capable of operating at satisfactory flux in aqueous solutions, and being low binding to organic biomaterials.

    摘要： This invention relates to a general method to surface modify porous membranes with a free radical polymerized polymer coating in a layer which is less than the thickness of the membrane. Another object of this invention relates to a general method to surface modify porous membranes with a free radical polymerized polymer coating to a predetermined and controlled depth from a first facial surface. Another object of this invention is to provide a general method to surface modify porous membranes with a free radical polymerized polymer coating into a pattern on one or both facial surfaces, the pattern maintaining its form to a controlled depth into the membrane. Membrane modification is spatially controlled through the use of a polymerization preventing agent (PPA), which prevents modification from occurring in defined spatially volumes of the membrane. The invention relates to porous membranes surface modified by the methods described.
