Abstract :
In this research, three nanocomposites including HMS and MCM coated by conductive polymers and a quaternized MOF were used as additive of polysulfone membrane to improve physio-chemical properties of the mixed matrix membranes. It was found that the quaternized ammonium agent immobilized on UiO-66-NH2 increased pure water flux and porosity of the membrane more than polyaniline and polypyrrole coated on MCM-41 and HMS, respectively. It was also observed that the migration of hydrophilic nanocomposites towards the aqueous phase during phase inversion of the casting solution increased the porosity and permeability of the membrane. The results showed that the quaternized MOF exhibited the highest value of the surface potential resulting higher hydrophilicity and permeability of polysulfone membrane and faster diffusion of water molecules.
