PES with the compositions of 18 wt is prepared for each dope solution. During the membrane casting process, 0 to 5 minutes delay prior to immersion in coagulant bath is set in order to allow solvent evaporation to take place. Water is used as the non-solvent for solvent exchange process. The prepared membranes are characterised based on their morphological aspect using scanning electron microscopy towards the effect of solvent evaporation time and solution viscosity. The changes in proton conductivity, methanol permeability, water uptake and hydrophilicity/hydrophobicity behaviours are also studied. Conclusively, the 18 wt PES membranes prepared with DMAc as solvent at 3 minutes solvent evaporation time exhibited desirable pore size for proton conduction (0.04 Ã? 10â??3 Scmâ??1) and methanol resistant effect that consequently contribute to considerably low methanol permeability rate at 0.06 Ã? 10â??7 cm2 sâ??1 which could elevate the direct methanol fuel cell performance. © 2020 John Wiley & Sons Ltd VL - 45 JF - International Journal of Energy Research ER -
