Commercial polyvinylidene difluoride (PVDF) membrane and another membrane which was composed of PVDF and FMWCNTs used to remove organic compounds from a water using the vacuum membrane distillation (VMD) method. SEM analysis, FTIR, and contact angle to examine the pore size and porosity and the hydrophobicity nature of the membrane to establish the permeate side's quality and quantity, the properties of PVDF/FMWCNTs nanocomposites (NCs), which were created by phase inversion, and the crystal structure of poly(vinylidene fluoride) (PVDF) were examined in relation to the effects of multiwall carbon nanotube (MWCNT) inclusions. Our results suggest that the effects of FMWCNT inclusions on the PVDF crystallization process are highly dependent on the exact melt treatment and subsequent cooling procedure. The addition of FMWCNTs causes the membrane's porosity and mass transport-available pores to rise. It also decreases hydrophobicity, as seen by the sudden decline in the contact angle. The fabricated membranes conducted in VMD cell to evaluate the total permeate reflux of ethanol separation from ethanol water mixture.
