The influence of various additives of PEG (with MW = 1000, 4000 g/mol), PVP (with MW = 10000, 29000 g/mol) and Pluronic F-17 on the attributes and performance of the EPVC and EPVC/boehmite nanocomposite membranes was studied. Water contact angle, scanning electron microscopy (SEM), atomic force microscopy (AFM) and energy dispersive X-ray (EDX) analyses and also the obtained results of pure water flux, bovine serum albumin (BSA) flux and flux recovery ratio (FRR) were evaluated to investigate the membrane attributes and performance. By adding 2 wt.% of PEG4000 to the matrix of the EPVC and EPVC/boehmite nanocomposite membranes, surface hydrophilicity, mean pore diameter and surface porosity improved. The nanocomposite membrane fabricated in the attendance of hydrophilic additive of PEG4000 exhibited the highest amount in pure water flux (701.4 L/m2.h), BSA solution
