Abstract In the present study, polybenzimidazole (PBI) polymer which has a great importance in polymer
electrolyte membrane (PEM) research was synthesized via the solution polycondensation method,
under various synthesis conditions to put forward the effect of the synthesis parameters on the
properties of the synthesized polymer and consequently to the quality of the prepared polymer
electrolyte membrane. The synthesized polymers were characterized in terms of their chemical
structure, thermal degradation behaviour, and molecular weight by Fourier transform infrared
spectroscopy (FTIR), nuclear magnetic resonance spectroscopy (1
H NMR), thermogravimetric
analysis (TGA). The Mechanical properties, acid-doping level capacity, proton conductivity, and
fuel cell… More >
