Abstract：

 In this work, Cu(tpa) nanocrystals were synthesized by stirring at room temperature and were introduced into PVDF membrane as modifier to prepare Cu(tpa)/PVDF hybrid ultrafiltration membrane. Cu(tpa) nanocrystals were characterized by XRD, FT-IR and SEM. The effects of Cu(tpa) nanocrystals and their contents on the morphology, structure and properties of Cu(tpa)/PVDF hybrid ultrafiltration membrane were systematically studied. The hybrid membrane was characterized by SEM, XRD, FT-IR andstatic water contact angle technique etc.The results showed that Cu(tpa) nanocrystals effectively regulated the internal morphology of PVDF membrane. When the content of Cu(tpa) was 5 wt%, the inside of the Cu(tpa)/PVDF membrane was entirely occupied by a spongy-like structure.  Properties test results showed that  the additon of Cu(tpa) material can significantly increased the pure water flux of PVDF wihile maintaining its BSA rejection above 96%. In addition, the BSA static adsorption and recovery water flux test showed that the Cu(tpa)/PVDF membrane had good anti-fouling performance.
