Moisture-Swing Polymer@textile Composites for CO2 Capture

Quaternary ammonium-containing sorbents have significant potential in direct air capture (DAC) of CO₂. In DAC sorbents, the adsorption of CO₂ can occur at lower concentrations, which allows for mitigation of global warming caused by the excess CO₂ already in the atmosphere. The project investigates the modification of textiles into polymer@textile composite membranes with improved mechanical properties for long-term stability and DAC performance. This is done by immobilizing polymeric sorbents with quaternary ammonium groups into the textiles. Future work includes investigating discarded textiles as a sustainable material in DAC membranes.
