Abstract

Polyethersulfone ultra- and microfiltration membranes were produced by grafting the temperature-sensitive polymer, poly(N-isopropylacrylamide) on the corona discharge treated membrane surfaces. The amount of the temperature-sensitive polymer grafted on the surface of the substrates was determined gravimetrically, and the surface morphology was analysed using SEM, as well as FTIR-ATR spectroscopy. The flow rate of distilled water through the grafted membranes was measured in a filtration unit, where temperature, water flux and pressure were controlled. The flux rate through the obtained temperature sensitive membranes increased notably when the temperature was raised from 30°C to 40°C.
