Abstract: Poly(2,5-benzimidazole) (ABPBI)—a promising high-temperature polymer electrolyte membrane—is characterized over a wide range of temperature (−50 to 220 °C) using broadband dielectric spectroscopy (BDS) to understand the various relaxation processes. The undoped ABPBI membrane shows two major… read more here.
