摘要： The present invention provides an ultrafiltration membrane comprising a sulfone polymer membrane matrix with pores and an organic polymer sealing layer, wherein the pores are filled with nanoadsorbents. The present invention further provides a method for preparing the ultrafiltration membrane, which includes the following steps: (1) synthesizing nanoadsorbents; (2) preparing the sulfone polymer membrane matrix by immersion-precipitation phase inversion; and (3) immobilizing nanoadsorbents in the pores of the sulfone polymer membrane matrix by reverse filling, then sealing the pores with organic polymers to form a multifunctional ultrafiltration membrane. In the present invention, colloidal gold, polyethylene glycol molecules and Pb(II) ions (and so forth) are utilized as models of viruses, macromolecular organic pollutants, and small molecular pollutants, respectively. It is shown that the multifunctional ultrafiltration membrane allows for removal of multiple pollutants from water and can simultaneously remove multiple pollutants under low pressure.

摘要： A system is provided for separating a bodily fluid, such as blood, into two or more constituent parts. The system is configured to cooperate with a fluid flow circuit including a spinning membrane-type fluid separation chamber having a housing, with a fluid inlet port and at least one fluid outlet port. A rotor is positioned within the housing so as to define a gap between the rotor and an inside surface of the housing, with the rotor being rotatable relative to the housing about an axis. A membrane is mounted on the rotor and/or on the inside surface of the housing and faces the gap to separate bodily fluid within the housing into two or more constituent parts. The membrane includes an anti-thrombogenic material, which may be either incorporated into the material of the membrane or coated onto at least a portion of the membrane.
