Immobilization and characterization of carbonic anhydrase on the surface of hollow fiber membrane of polymethyl pentene
碳酸酐酶在聚甲基戊烯中空纤维膜表面的固定及其性能分析

We immobilized carbonic anhydrase (CA) onto the surface of membrane oxygenator of polymethyl pentene (PMP) to enhance the removal of carbon dioxide in blood by two steps. We first introduced hydroxyl groups onto PMP surface by water plasma treatment, and then coupled CA onto PMP surface by using cyanate bromide (CNBr) as a crosslinker. After plasma treatment, the contact angle with water and chemical composition of PMP surface were characterized by analysis system of surface contact angle and XPS. Using p-n...
