| 英文摘要 | Dopamine modified sodium montmorillonite (D-MMT) was firstly used as the inorganic filler of polyvinylidene fluoride (PVDF) composite membranes via nonsolvent induced phase separation (NIPS) method. The surface modification sodium-montmorillonite (Na-MMT) was characterized by Fourier transform infrared (FTIR), thermo gravimetric analysis (TGA), X-ray diffraction (XRD) and transmission electron microscopy (TEM). The X-ray photoelectron spectroscopic (XPS) spectra and elemental mapping demonstrated that the D-MMT was incorporation and uniformly dispersed into PVDF composite membranes. Results showed that the incorporation of D-MMT into PVDF composite membranes significantly improved the mechanical property and hydrophilicity at a low D-MMT loading. The addition of 0.8 wt% D-MMT not only altered the morphology and structure of membranes, but also drastically increased tensile strength from 1.98 to 2.63 Mpa while elongation at break increased from 58% to 126%. In addition, the pure water flux of membranes increased by almost 50% from 15 to 22 L m(-2) h(-1) when 0.8 wt% D-MMT was added. These results suggested that the surface modification of Na-MMT played an important role inimproving mechanical properties and pure water flux of PVDF composite membranes. |
