Non-radiation polyethylene-based anion exchange membrane (AEM) was synthesized by chemical grafting 4-vinylbenzyl chloride (VBC) on it with the presence of benzoyl peroxide as the initiator. The effect of various styrene additions to membrane properties were assessed in this study. The result AEM with 10% styrene addition has peak IEC value, 57% higher than non-styrene AEM. Water uptake and mechanical properties was slightly enhanced with the presence of styrene. The addition of styrene improves compatibility between VBC and low-density polyethylene due to the formation of compatibilizer of poly(styrene-co-VBC). These were evidenced by elemental analysis, elemental analysis, infrared spectroscopy, 1H NMR and field emission-SEM.
