This work describes the first report of the use of an aminosilicone solvent mix for the capture of CO 2 . To maintain a liquid state, a hydroxyether co‐solvent was employed which allowed enhanced physisorption of CO 2 in the solvent mixture. Regeneration of the capture solvent system was demonstrated over 6 cycles and absorption isotherms indicate a 25–50 % increase in dynamic CO 2 capacity over 30 % MEA. In addition, proof of concept for continuous CO 2 absorption was verified. Additionally, modeling to predict heats of reaction of aminosilicone solvents with CO 2 was in good agreement with experimental results.
