Effects of Morphology of Multicomponent Polymer Membranes Containing Calixarene on Permselective Removal of Benzene from a Dilute Aqueous Solution of Benzene

摘要: This paper focuses on the structural characteristics of membranes used in removal benzene from a dilute aqueous solution by pervaporation. Poly(methyl methacrylate)-graft-poly(dimethylsiloxane) (PMMA-g-PDMS) and poly(methyl methacrylate)-block-poly(dimethylsiloxane) (PMMA-b-PDMS) containing tert-butylcalix[4]arene (CA), (CA/PMMA-g-PDMS CA/PMMA-b-PDMS) were studied. When an 0.05 wt % was permeated through CA/PMMA-g-PDMS CA/PMMA-b-PDMS membranes, these showed strong permselectivity. Both permeability permselectivity enhanced increasing CA content, due to affinity for benzene. The much greater than those membranes. Transmission electron microscope (TEM) observations revealed that both had micr...
