(452c) New Poly(alkyl imines) for CO2 Capture from Ambient Air
In this work, we present work towards the development of a series of new poly(alkyl imines) as well-defined branched molecules for CO2 capture. By changing the structure and flexibility of the adsorbent aminopolymer, we show that the CO2 capture capacity and efficiency can be readily tuned. These materials represent a departure from the traditionally-studied poly(ethylenimine) (PEI) for CO2 capture by using a well-defined molecular species with controlled and varied alkyl linker length. Additionally, these structures only contain primary and tertiary amines, which impart high capture capacity under ultradilute conditions and stability against oxidative degradation.
