| Abstract: | The action of different solvents, different usage of the solvents and mixed solvents on PVDF film by the phase of separation method is discussed. The properties of the PVDF membrane measured by the porosity of film and the air resistance. The results shown that the membrane with the production of the single solvent system DMAc 65mL or the mixed solvent DMAc： DMF： NMP for 15： 16：17 obtained by the porosity of the membrane were 87. 11% and 91.23% respectively,the windage of Membrane were 167.2Pa and 180Pa, which has been basically in line with the requirements of industrial application. |
