Polyethyleneimine (PEI)-impregnated carbon fabrics are structured direct air capture (DAC) sorbents whose electrical conductivity enables resistive temperature swing regeneration. However, how substrate morphology translates intrinsic sorbent properties into module-scale DAC performance under continuous flow remains poorly understood. The authors investigate this using a resistively heated spiral wound module (SWM). Two carbon fabrics, a macroporous non-woven (E20) and a microporous activated carbon cloth (FM10), were characterized.
