CO2-switchable Materials: Solvents, Surfactants, Solutes and Solids

CO₂-responsive materials are a relatively recent innovation. In general, stimuli-responsive materials exhibit reversible changes in their physical or chemical properties in response to external triggers such as temperature, pH, light, or voltage. However, there are often limitations in applying these triggers including economic and environmental costs, and product contamination. The realization that CO₂ can be used as an effective trigger for stimulating changes in material properties has p...
