Nano composite Membranes of proton conducting polymer electrolytes by using polyhedral oligomeric silsesquioxane having Sufonic acid group |
摘要 |
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.
