▎ 摘　　要

The pervaporative performances of pristine polydimethylsiloxane (PDMS) membrane and modified one by hybridizing with graphene nanosheets (PDMS-G) were evaluated for phenol removal from aqueous solutions. The incorporation of hydrophobic graphene nanosheets could enhance the process performance. The optimum performance was determined at 0.2 wt% crosslinker concentration and 0.2 wt% graphene content with a significant improvement in the separation factor up to 42.35. The enhanced separation factor can be attributed to optimized interfacial free volume in the structure of the membranes and formation of pi-pi interactions between graphene and phenol. The effects of operating parameters on separation performance were also evaluated. [GRAPHICS]
