Surface engineering of macroporous polypropylene membranes

The surface properties of polymer membranes are crucial to their application. This Review provides concise comments on surface engineering strategies for macroporous polypropylene membranes. The applications of surface engineering concepts in membrane-based bioreactors, bioseparation, biosensing, biosynthesis, environmental analysis, water purification, energy technology, medical devices (artificial lung and liver), and some novel separation processes (intelligent membrane separation) are summarized. The prospect of surface engineered biomimetic polypropylene membrane is also looked at.
