文摘

A pyrimidine-bridged organoalkoxysilane membrane was designed and synthesized. A sterically hindered amine was employed for CO2 separation membranes. BTPP membranes demonstrated an improved efficiency for CO2 transport. A new concept of a “mild affinity membrane” for CO2 transport was proposed.
