FLUORINATED NANOCOMPOSITE MEMBRANE COMPRISING POLYHEDRAL OLIGOMERIC SILSESQUIOXANE WITH PROTON DONOR AND PROTON ACCEPTOR AND METHOD OF PREPARING THE SAME

摘要

The present invention relates to a proton-conductive nano-composite membrane in which polyhedral oligomeric silsesquioxane (POSS) with a proton donor and POSS with a proton acceptor are introduced into a fluorinated proton-conductive polymer membrane, and also relates to a method for preparing the same. Both POSS with a proton donor and POSS with a proton acceptor are added to the nano-composite membrane of the present invention, and thus generated protons (positive ions) are easily hopped within an ion channel, thereby increasing ion conductivity. Furthermore, a size of POSS used in the present invention is considerably small, and thus POSS rarely obstructs movement of protons in the ion channel within the polymer membrane, thereby realizing desirable proton conductivity.
