Comparative Stuy of Anion Exchange Membranes Prepared by Brominated Polyphenyene Oxide Polymers Myint Myint Khaing Myat Kyaw Thu Ayemon Thida Nyo Soe Tun Myaing This research was designated to find out the solution for solving energy shortage problems of globe. There were three different brominated polyphenyleneoxide(BPPO) membranes such as 45% BPPO membrane, 35% BPPO membrane and 30% BPPO membrane that were prepared by dissolving BPPO polymer in dimethyl formamide (DMF) with the assistance of magnetic stirrer. Moreover, the prominent functional groups of each BPPO membranes were identified by Fourier Transform Infrared (FT IR) spectroscopy that informs the presence of distinct C-Br stretching band at 1019.66 cm-1. The Ion-Exchange Capacity (IEC) value of each membrane was determined by Mohr titration method where as 45% BPPO membrane gave 1.42 mmolg-1 IEC value which is a suitable result for Anion Exchange Membrane (AEM) and this value was highr than other two BPPO membranes. The resistance values of membranes were investigated by Multi-Meter that was related the conductivity of membranes and the swelling ratio, the solubility of each membrane were detected by dipping membranes in various solvents. 2018 http://hdl.handle.net/20.500.12678/0000000630 https://meral.edu.mm/records/630
