COPOLYMER COATING FOR A HYDROPHOBIC MEMBRANE

摘要

A coating material and a method for coating a hydrophobic membrane with a copolymer that contains at least one hydrophilic segment and at least one hydrophilic segment, such as a PEO-PPO-PEO triblock copolymer, so that the surface of the membrane becomes hydrophilic. The hydrophilic coating helps repel biological molecules, thereby reducing the risk that these molecules will adsorb or deposit on the membrane surface. When the copolymers are modified with an active group, ligands can be immobilized on the copolymer through the active group so that specific molecules that will bind with the ligands cna be targeted for immobilization on the copolymer coating, thereby improving the efficiency of the removal of specific targets.
