| Abstract: | The preparation of PVDF hollow fiber composite membrane and its properties was studied. The results of FTIR and SEM showed that the crosslinking reaction of PVA by glutaradehyde occurred on the surface of PVDF hollow fiber membrane, thus a composite membrane formed, and the properties of PVDF hollow fiber composite membrane was visibly influenced with reaction conditions,such as soakage time, concentration of PVA, reaction time, reaction temperature and so on. With the reaction temperature and reaction time increased, the flux of PVDF hollow fiber membrane was lowered, and the retention rate of membrane was improved. |
