제목 ultrafiltration membranes having having hydrophilic and antibacterial properties by grafting the surface treated carbon nano-onions to the sulfonated polyethersulfone
초록 An ultrafiltration membrane with high water flux and antibacterial properties was prepared from sulfonated poly(ethersulfone) (sPES) and carbon nano-onions (NO) containing various functional groups. Nitration of PES and the reduction of nitro groups in the PES were performed to prepare PES-NH2. NO prepared from the nanodiamonds (ND) by the thermal annealing was functionalized with hydroxyl groups. To introduce NO into the membrane, NO grafted with sPES (sPES-g-NO) was prepard by grafting sPES on NO surface to maximize interfacial adhesion energy. The PES and sPES membranes did not exhibit antibacterial activity, whereas the PES membranes containing functionalized NO exhibited antibacterial activity, regardless of the functional groups on the NO. The MWCO of the sPES-g-NO becomes higher as the sPES concentration increases. The water flux of the sPES-g-NO membrane was much higher than that of the PES membrane.
