Study on the Chemical Stability of Mechanochemically Modified Polyvinylchloride (PVC) Membrane

Abstract:

A ball mill was used to mechanochemically modified Polyvinylchloride (PVC) powders. PVC membranes before and after mechanochemical modification were prepared at different dope solution temperatures 60°C. The modified PVC membrane was immersed in HCl solution, NaClO solution and NaOH solution, the permeation flux and mechanical properties of the PVC membranes before and after post-treatment were studied. The results showed that, modified PVC membrane owned good ability of resistance to acid and alkali, NaClO solution had a strong oxidizing, it generated the polar group made the surface of PVC membrane more hydrophilic, the permeation flux improved. The strong oxidizing of NaClO solution made the skin layer of PVC membrane more thinner, the tensile strength decreased.
