Preparation of PBI/PPA Membranes for High Temperature PEMFCs
碩士 === 元智大學 === 化學工程與材料科學學系 === 99 === In this thesis, we synthesized polybenzimidazole (PBI) from 3,3’-diaminobenzidine and isophthalic acid . The molecular weight of PBI determined by GPC (gel permeation chromatography) with polystyrene as a standard was Mw = 2.05×105 g/mol. The polymerized find p...
