Ye Wang, Ting-Ting Hu, Xiao-Long Han, et al. Fabrication of Cu(OH)2 Nanowires Blended Poly(vinylidene fluoride) Ultrafiltration Membranes for Oil-Water Separation[J]. Chinese Journal of Polymer Science, 2018, 36(5): 612-619. DOI: 10.1007/s10118-018-2041-y.
Cu(OH)
2
nanowires were prepared and incorporated into poly(vinylidene fluoride) (PVDF) to fabricate Cu(OH)
2
-PVDF ultrafiltration (UF) membrane
via
immersion precipitation phase inversion process. The effect of Cu(OH)
2
nanowires on the morphology of membranes was investigated by X-ray photoelectron spectroscopy (XPS)
Fourier transform infrared (FTIR) spectroscopy
atomic force microscopy (AFM)
scanning electron microscopy (SEM) and X-ray diffraction (XRD) measurements. The results showed that all the Cu(OH)
2
-PVDF membranes had wider fingerlike pore structure and better hydrophilicity
smoother surface than pristine PVDF membrane due to the incorporation of Cu(OH)
2
nanowires. In addition
water flux and bovine serum albumin (BSA) rejection were also measured to investigate the filtration performance of membranes. The results indicated that all the Cu(OH)
2
-PVDF membranes had high water flux
outstanding BSA rejection and excellent antifouling properties. It is worth mentioning that the optimized performance could be obtained when the Cu(OH)
2
nanowires content reached 1.2 wt%. Furthermore
the membrane with 1.2 wt% Cu(OH)
2
nanowires showed outstanding oil-water emulsion separation capability.
