In this study. polyethersulfone (PES) membranes blended with zinc oxide nanoparticles (ZnO) were manufactured by diffusion induced phase inversion in NMethyl-pyrrolidone (NMP) as solvent and deionized water as coagulant. in view of increasing the properties of the polymeric membranes. Neat PES membranes were modified by dispersing ZnO nanoparticles with two different sizes in a PES ca... https://parisnaturalfoodes.shop/product-category/vitamin-e-400iu/
