The modification methods of polymer membrane materials
Zhou Gui · 2003
The modification methods of polymer membrane materials was reviewed.In order to improve hydrophile and flux of membrane ,it can be use the surfactant modified membrane.Solvent modified membrane is made with preoperation of certain solvent in some time and temperature. The blend modified operation is simpleness and facilitation. The blend modified membrane makes use of advantage of its components and avoid its disadvantage.The development of plasma modification technique is fast,and it has excellent properties,such as simpleness,safety and no pollution.Radiation grafting offers an attractive way for the modification of membranes in order to enhance to contradict stain and hydrophilic propertie of membranes.
