Alumina Incorporation in Self-Supported Poly(ethylenimine) Sorbents for Direct Air Capture
{{output}}
Self-supported branched poly(ethylenimine) scaffolds with ordered macropores are synthesized with and without Al2O3 powder additive by cross-linking poly(ethylenimine) (PEI) with poly(ethylene glycol) diglycidyl ether (PEGDGE) at -196 °C. The scaffolds' CO2 u... ...
