Abstract
Poly(4-vinyl pyridine) nano-spheres (P4VP-NS) stabilized poly(vinyl phosphonic acid) (PVPA) membranes were prepared as proton conducting membranes for fuel cells. The acid–base interactions between P4VP-NS and PVPA were utilized to improve the dimensional and thermal stability of PVPA. In this work, the effects of acid–base interactions on proton conductivity and thermal stability were quantitatively determined and discussed based on the results of 1H magic-angle-spin NMR (1H MAS NMR), Fourier transfer infrared spectroscopy (FTIR) and impedance spectroscopy measurements.
