摘要

CNT-PVA membrane was fabricated and compared with polymeric membranes.

The separation performance was evaluated by homemade and cutting fluid emulsions.

The three membranes show similar oil retention rates.

CNT-PVA membranes have higher permeation fluxes compared with polymeric membranes.

CNT-PVA membrane shows higher fouling resistance.
