| Research Abstract |
Hemocompatibility is one of the most important properties for homodialysis membranes. For improvement of the hemocompatibility on a cellulose dialysis membrane, modifications with new blood compatible phospholipid polymers were carried out. These methods incluuded a direct grafting of the phospholipid monomer on the membrane surface, coating the membrane surface with a water-soluble graft copolymer composed of a cellulose backbone and phospholipid polymer as a branch, and covalent bonding with a reactive phospholipid polymer on the membrane surface. These modified membranes could reduce protein adsorption, complement activation, and platelet adhesion on the surface without any adverse effects on the membrane perfomance.
