Title:
PRODUCTION OF PLASMA TREATED MEMBRANE FOR CARBON DIOXIDE SEPARATION
Document Type and Number:
Japanese Patent JP2521883
Kind Code:
B2
Abstract:
PURPOSE: To produce a carbon dioxide separation membrane excellent in the separation factor of carbon dioxide and the holdability of a carbon dioxide carrier liquid and not lowered in its membrane capacity even by the contact with water.
CONSTITUTION: After a porous polymeric membrane is subjected to plasma treatment, hydrophilic vinyl monomer vapor is brought into contact with the plasma treated porous polymeric membrane to be subjected to graft polymerization and, subsequently, a carbon dioxide carrier liquid is impregnated into the porous polymeric membrane having the hydrophilic polymer surface layer thus obtained to be held thereto.
