Microwave-Assisted Synthesis of Novel Polybenzimidazole Resin and Performance of Its Proton Exchange Membranes

doi:10.7503/cjcu20121158

Abstract

Abstract:

A series of novel aliphatic polybenzimidazole(PBI) copolymers was synthesized from 3,3'-diaminobenzidine, adipic acid and 2,6-pyridinedicarboxylic acid by adjusting the molar ratio of adipic acid and 2,6-pyridinedicarboxylic acid via solution condensation reaction in poly(phosphoric acid) with microwave synthetic method which is timesaving relative to conventional ways. The casting PBI membranes made from the copolymers were characterized mainly by Fourier transform infrared spectrometer(FTIR), thermogravimetric analyzer(TGA), water uptaking, swelling ratio, proton conductivity, tensile strength as well as Fenton test. Among the membranes, the PBI-C₂ membrane made from the resin by polymerization using adipic acid and 2,6-pyridinedicarboxylic acid in a molar ratio of 3: 2, showed good proton conductivity as high as 30 mS/cm at 160℃ after doped with H₃PO₄. The tensile strength(77.54 MPa) and elongation at break(39.25%) were measured at room temperature. By dynamic mechanical thermal analysis(DMTA), the parameters including the maximum storage modulus(9.0623 MPa), the maximum loss modulus(8.36 MPa) and glass transition temperature(360℃) were obtained. The Fenton test indicates that PBI-C₂ membrane has good anti-oxidative stability. The results suggest that the PBI-C₂ membranes show a promising application in high temperature proton exchange membrane fuel cell.
