摘要: Poly(vinylidene fluoride‐co‐hexafluoropropylene) (PVDF‐HFP) microporous membrane was prepared by supercritical CO2 extraction of dibutyl phthalate (DBP) template from PVDF‐HFP/DBP film. The effects conditions such as pressure, temperature, and time on efficiency the porosity were studied. DBP size stability polymer during compared with those solvent process. structure resulting characterized scanning electron microphotograph (SEM), X‐ray diffraction (XRD) differential calorimeter (DSC). With increasing pressure time, increased. Maximum is obtained at temperature higher than 18 MPa 75°C, respectively. membranes depended shrinkage ratio membranes. Compared e...
