Green and low-carbon development is a concept of life advocated by people all over the world.The annual increase of CO2 emissions has huge impact on production,life and climate change.It is effective method to separate and purify CO2 from fossil energy emission gas.Membrane separation has more advantages than other methods in the current relatively mature collection methods.A kind of polymer containing polyimide group was selected as membrane material.To explore the intermolecular bonding characteristics of the monomers in the preparation process of the base membrane.Through the introduction of special functional groups,thermal crosslinking,chemical crosslinking and other modification methods in the synthesis process,the CO2 separation and capture membrane with better comprehensive performance can be prepared.It had great application prospect in large-scale separation and purification of CO2.
