| description | 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, polyethyleneimine was immobilised onto the surface of silica
before added into poly(4,4’-diphenylether – 5, 5’-bibenzimidazole) (OPBI). Nuclear Magnetic Resonance (NMR) experiment
proved the synthesised polymer while Fourier-transform infrared spectroscopy (FTIR) and EDX method used to validate the
grafting of the amine derivative to the surface of silica in the polymer matrix. Although a satisfactory dispersion pattern
was found on all nanocomposite membrane under scanning electron microscope (SEM) studies, agglomeration pattern was
seen at higher loading of functionalised silica nanoparticles. The physicochemical characteristic of the nanocomposite
membrane was investigated by using thermogravimetric analysis for high temperature PEMFC application. Lower water
uptake and swelling ratio in both water and phosphoric acid (PA) showed by the OPBI / SiPEI with an increasing trend as
the amount of SiPEI were increased. Addition of amine functionalised silica into OPBI shows a significant improvement
compared to pure OPBI while the thermal stability of the membrane at high temperature region (100 – 200 °C) can be
influenced by the loading concentration of the amine functionalised silica. |
