In this work, the UiO-66-GO/ Polyvinylidene fluoride (PVDF) flat membranes were prepared by nonsolvent-induced phase separation (NIPS), the synthesis of the UiO-66-GO composites were carried out through hydrothermal and Solvothermal method[1-4]. The effect of the contents of GO was studied. Additionally, the novel membranes were characterized by XRD, FTIR and AFM. The XRD demonstrates that GO did not influence the crystal structure of UiO-66, the FTIR shows that there is no new chemical bonds between UiO-66 and GO, and the AFM exhibits that surface roughness was reduced to 46.5nm. Specifically, the membranes exhibited high flux and rejection when the contents of the GO were 6wt%, the water flux was enhanced to 88.42%, the rejection of BSA was increased to 95.77%, the water contact angle was decreased to 62.21°, The good properties of the UiO-66-GO/PVDF composite membranes make it possible to be a good potential candidate for water treatment.
