  Abstract:

  Biomimetic mineralization method was employed to deposit CaC_{O3particles on the surface of carboxylated tannic acid modified polyvinylidene fluoride (PVDF) microfiltration membrane to prepare superhydrophilic PVDF@C-TA@CaCO3membrane. The effects of concentration of mineralized solution (CaCl2?and Na2CO3solutions) and alternate impregnation times on PVDF@C-TA@CaCO3membrane were investigated by using water contact angle and pure water flux as evaluation indexes. With the increase of the concentration of mineralized solution and the number of alternate impregnation, the water contact angle of PVDF@C-TA@CaCO3membrane decreased gradually, and the pure water flux increased first and then decreased. When the concentration of mineralized solution was 0.15 mol/L and alternate impregnation for 10 times, the pure water flux of PVDF@C-TA@CaCO3membrane reached the maximum of 5 750 L/(m^{2·h), and the water contact angle decreased to 10°. The retention rates of PVDF@C-TA@CaCO3membrane to vegetable oil, cyclohexane and petroleum ether emulsion were 90.5%, 93.3% and 91.5%, respectively, and the flux recovery rates were 88.5%, 94.4% and 95.5%, respectively, showing good separation performance of oil-water mixture.}}
