Synthesis and characterization of sulfonated mutiphenyl conjugated polyimide for PEMFC
E-mail:
A new monomer, di-sulfuricacid-1,1-bis(4-aminophenyl)-2,2-diphenylethylene (SBAPDPE), was synthesized by direct sulfonation of the parent diamine, 1,1-bis(4-aminophenyl)-2,2-diphenylethylene (BAPDPE) using concentrated sulfuric acid. A series of the side-chain-type sulfonated conjugated tetraphenylethylene polyimides (SCTPPIs) with different degrees of sulfonation were prepared from dianhydrides with SBAPDPE and non-sulfonated diamine. The SCTPPIs generally showed good solubility in m-cresol and DMSO. The membranes were studied by FT-IR, 1H NMR spectroscopy, and TGA. Sorption experiments were conducted to observe the interaction of sulfonated polymers with water. The ion exchange capacity (IEC) and proton conductivity were evaluated with increase of degree of sulfonation.
