What is Enhancing membrane performance in removal of hazardous VOCs from water by modified fluorinated PVDF porous material about?

Fluorinated membranes have significant importance in separation due to their inertness, fouling resistance. A novel modification methodology of poly(vinylidene fluoride) (PVDF) membranes was developed employing piranha reagent to activate the fluorinated surface followed by consecutive grafting with 1H,1H,2H,2H-Perfluorooctyltriethoxysilane (FC6). Membranes were implemented in membrane distillation for the removal of hazardous volatile organic compounds (ethyl acetate - EtAc) from water. Octyl group functionalized membranes were also tested for comparison. Membranes were characterized using AFM, ATR-FTIR, SEM, DSC, XRD, goniometric and porometry techniques. Results showed a significant improvement in the membrane performance. Flux of EtAc and PSI changed in the following way between pristine (JEtAc = 1.8 kg h−1 m−2, PSI = 33 kg h−1 m−2) and 1-min activated membrane (JEtAc = 3.0 kg h−1 m−2, PSI = 72 kg h−1 m−2). Furthermore, for functionalized sample with FC6 the performance was following JEtAc = 5.2 kg h−1 m−2 and PSI = 227 kg h−1 m−2. The activation and functionalization influenced significantly material properties. Higher roughness, contact angle and more open structure were noti
