- W4385618371 abstract "Direct air capture (DAC) is a promising tool for reducing CO2 concentrations in the atmosphere and fighting climate change. We synthesized a series of quaternary ammonium (QA)-functionalized poly(arylene ether sulfone) copolymers with varying mole fractions of charge content and demonstrated their potential as sorbents for DAC. Molecular weight analysis determined that a high monomer conversion was achieved in <6 h and relatively high molecular weights for all copolymer compositions. Thermal analysis revealed that all polymers had degradation temperatures >240 °C and a single glass-transition temperature (Tg); Tg decreased with an increase in ion exchange capacity (IEC). Fractional free volume and water uptake percentage increased and water contact angle decreased with the number of QA sites when compared to a neutral, commercially available polysulfone (Udel P-1700 PSU). Next, the novel series of ammonium-functionalized copolymers exhibited a moisture-mediated capture and release of atmospheric CO2. When exposed to air containing 30% relative humidity, the polymers captured CO2, and the capacity increased with the IEC. When the relative humidity was increased to 95% the samples released CO2. This study demonstrates a promising CO2 DAC sorbent and highlights the possibility for continuous DAC with purpose-built freestanding membranes." @default.
