Reviewing fundamental and essential works of traditional membrane systems, advanced functional membranes are discussed with both organic and inorganic ones. Furthermore, for development of new field of membrane science and technology, electro-and photoactive functional membrane whose transporting guests are electron (hole) and photon, are described with several examples ; such as various devices of functional molecule incorporating conducting polymer membrane, ultrahigh anisotropic conducting polymer membrane, photoemission energy controllable membrane superlattice of quantum functional semi-conducting conjugating polymer multilayers membrane. These pioneering membranes shall play big drama of membrane science and technology in the future.
