Surface Modification by Graft Polymerization

Abstract

Membrane technologies have now been widely exploited and utilized on a large scale due to the unique separation principles of membranes. For further progress, however, membranes with favorable properties and functionabilities must be designed and prepared. Based on existing membrane materials, modification of them is necessary. Among different technologies, graft polymerization is a universal modification method for preparing a "tailored" membrane surface with desired functions. The grafted polymer chains on the membrane surface play an important role in membrane applications. In this chapter methods of graft polymerization on the membrane surfaces and the relative applications are introduced.
