Sulfonated poly (arylene ether ketone) (SPAEK) with hydroxyl group in end chain of polymer (SPAEKOH) was synthesized from bisphenol A, Ketone, S- Ketone and hydroxyl phenyl ethanol. SPAEKOH is precursor for ring-opening polymerization of lactide to form block copolymer. The porous will be fabricated from diblock copolymer SPAEK/PLA by selective remove on sacrificial block via degradable PLA in diblock copolymer. The using various amount of Lactide for synthetic block copolymer reaction, the different pore sizes were created in proton exchange membrane fuel cell in order to enhance ability of proton conductivity. Morphology of porous in membrane is observed by Scanning Electron Microscope (SEM). Properties of membrane such as water uptake, dimension swelling, thermal and mechanical stability especially proton conductivity will be investigated at different temperature. |
