Synthesis and physicochemical characterisation of amine functionalised SiO2 /PBI derivatives nanocomposite membrane

In this study, a series of amine functionalised silica/OPBI nanocomposite membrane for high-temperature polymer electrolyte fuel cell (HT – PEMFC) application were prepared. In order to provide a better dispersion and improving the interfacial interaction between organic/inorganic materials, pol...
