The fabrication of polymeric membrane from poly (vinylidene fluoride) (PVDF) polymer with N-methyl-2-pyrrolidinone (NMP) serves as a solvent is prepared using phase inversion method with several parameters to produce the optimum membrane condition. To produce the optimum polymeric membrane, the formation of finger-like structure needs to be increased by manipulating two major parameters, the coagulation bath medium (0 until 75 w/w% ethanol concentration) and evaporation time (0 minutes to 3 minutes) during phase inversion. Comprehensive material characterization techniques via scanning electron microscopy (SEM), fourier transform infrared (FTIR) spectroscopy, surface area analysis, porosity analysis and energy dispersive x-ray spectroscopy (EDS) were followed to ascertain the nature of the membrane fabrication and their inherent material properties. In membrane performance test using pervaporation experiment, the effect of feed temperature and feed flow rate was investigated in order to get the optimum membrane separation. Temperature 50oc with the flow rate 20 L/hr had become optimum condition for this process. Using PVDF membrane with 15 w/w% ethanol concentrations at 2 minutes evaporation time gives better selectivity with higher separation factor (32) and low permeation flux (4.9 kg m-2 hr-1) compared to other type of membrane. This type of membrane was improved by adding the ionic liquid and results in increasing the separation factor from 32 to 78. Meanwhile the permeation flux also increases from 4.9 kg m-2 hr-1 to 7.9 kg m-2hr-1.
