| Abstract: | In order to improve the hydrophilicity of PVC membrane,lignin/PVC membrane was prepared by polymer blending method.The cross-sectional morphology of the film was characterized by scanning electron microscope(SEM).The effects of lignin dosage,pore-forming agent type and dosage on the hydrophilicity of the membrane were studied by measuring the water absorption,porosity,membrane flux and membrane surface contact angle.The results showed that the lignin/PVC membrane had multilevel pores.After adding lignin,the water absorption,porosity,hydrophilicity and the membrane flux of the membrane were significantly improved.When the dosage of lignin was 0.06 g,the dosage of PVC was 3.0 g,and the action time of porogen was 10.5 h,the comprehensive performance of lignin/PVC membrane was the best.Compared with PEG400,the PPG200 and PEG200 with lignin had better hydrophilicity.When the dosages of PEG200 and PPG200 were 0.6 g,the surface contact angles of the membranes were 75.7°and 77.9°,the porosities were 12.6%and 7.1%,the water absorption rates were 114.7%and 94.8%,and the membrane fluxes were 135.5 and 372.6 L/(m2·h),respectively. |
