文摘

•: Carboxylated PIM–1 membrane are prepared for pervaporation dehydration of EG.
•: Carboxylation improves the hydrophilicity of the PIM-1 membrane.
•: The membranes allow fast permeation of water in the EG purification.
•: The membranes exhibit good water selectivity in the pervaporation.
•: Relationship between the hydrophilicity and pervaporation performance is presented.
