This research describes the modification of polyvinylidene fluoride (PVDF) ultrafiltration membranes by grafting poly (N-isopropylacrylamide) using surface-initiated atom transfer radical polymerization (SI-ATRP) in order to remove attached foulants during oily water filtration. The grafting process was studied at different polymerization time. Reaction time of 30 h was found as the best condition for ATRP process in this study. The flux decay ratio was 7.96% and the maximum of flux recovery ratio was 95.01% (after a cold water rinse) which obtained for the modified membrane at the best condition. Grafted membranes also exhibited good oil rejection (95.2%). Therefore, these easily cleanable membranes could be used to effectively separate emulsified oils from water at different temperatures
