Recent Advance of Responsive Polymers Applied to Carbon Dioxide Profile Control
CO2-responsive polymers are materials which properties or states can be reversibly changed after CO2 is introduced or discharged.Such polymers have significant value in suppressing CO2 gas channelling and enhancing oil recovery.In this paper,In this paper,the classification,molecular structure and response mechanism of CO2 responsive polymers are introduced.Besides,the synthesis of polymers and their application in CO2 profile control are reviewed,and their development direction and application perspective are also prospected.
