CO2 capture technology on the ISS is outdated and power-hungry process. It is known that ionic liquid (ILs) can physisorb CO2 with variable selectivity based on the IL structure. This work explores the development of novel fluoroalkyl ionic liquids paramagnetic properties, supported on a 3D printed ferromagnetic support structure. The ISS pressurized volume is nearly 920 m3, meaning the system will need to remove 4.29 mmol CO2 m-3 hr-1 for a 4 person crew, which requires fast kinetics and fast transport to remove enough CO2. By reducing PFIL surface tension and by optimizing paramagnetic susceptibility, we hope to induce a magnetocaloric convection across the magnetic support membrane, which will allow the system to perform beyond the diffusion rate limits of typical ILs and gain the advantages of forced convection with little to no power demand.
