Abstract： |
| Different types of membrane casting solution containing nano-SiO2were prepared by adding different kinds of surfactants and adding differentcontent of polyvinylidene fluoride (PVDF).The rheologyof membrane casting solution was studied from different aspects of adding surfactants, temperature, shear rate and PVDF content. The results showed that the casting solution with adding surfactants can get a better flow curve,and shear viscosity was decreased when temperature and shear rate was increased. Besides, the experiment found that the membrane casting solution had a critical shear rate value, the amount of PVDF has a great influence on the rheology and properties of casting solution. Some films were prepared using different types of casting solution and the properties and microstructure were tested.Theresults showed that different membranes had different performance and structure. |
