- •
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.
