Steric hindrance effect on amine demonstrated in solid polymer membranes for CO2 transport

▸ First study of steric hindrance effect on amine demonstrated in a solid phase. ▸ Effect enhanced the CO2 transport capacity of amines in a solid polymer film. ▸ Developed new membranes using sterically hindered polyamines as fixed carriers. ▸ New membranes showed much improved performance compared with literature data.
