Abstract: 본발명은프로톤주게(proton donor)를갖는폴리헤드럴올리고메릭실세스퀴옥산(POSS)과프로톤받게(proton acceptor)를갖는폴리헤드럴올리고메릭실세스퀴옥산(POSS)이술폰기를갖는방향족탄화수소고분자막에도입된양성자전도성나노복합막및 이의제조방법에관한것이다. 본발명의나노복합막에는양성자주게를갖는 POSS와양성자받게를갖는 POSS가함께첨가되어있어발생된양성자(양이온)가이온채널내에서수소결합을통해쉽게호핑(hopping)되어이온전도도가증가된다. 또한, 본발명에사용된 POSS는그 크기가매우작아고분자막내 이온채널에서양성자의이동을거의방해하지않으므로우수한양성자전도도를구현할수 있다. 또한, 본발명에의한양성자전도성나노복합막은고분자막의술폰화도를높였음에도불구하고우수한기계적강도를보여준다.

Abstract: PURPOSE: A proton-conducting polymer nanocomposite film has excellent proton conductivity even at high temperatures and has excellent mechanical strength superior than conventional PEMFC fluorine-based polymer film. CONSTITUTION: A proton-conducting polymer nanocomposite film is that a sulfonate group-introduced silsesquioxane is mixed to a proton-conducting polymer substrate. A manufacturing method of the proton-conducting polymer nanocomposite film comprises a step of dissolving a fluorine-based proton-conducting polymer substrate into a solvent; a step of dissolving a sulfonate-introduced silsesquioxane into a solvent; a step of mixing the fluorine-based polymer substrate solution and the silsesquioxane solution; a step of ultrasonic waves-treating the mixed solution and dispersing silsesquioxane in the fluorine-based polymer; and a step of carrying out a casting in a vacuum oven and removing residues.
