Abstract

We found that our optically CO₂ -responsive polydimethylsiloxane (PDMS) elastomer rapidly and reversibly underwent both visible and fluorescent color changes in the presence of CO₂ gas. Unlike conventional optically CO₂ -responsive polymeric materials, it functions in totally dry gaseous conditions. The visible color and fluorescence of the elastomer sheet change after only 1 min of exposure to CO₂ , and the sheet exhibits excellent repeatability in terms of color switching that persists for at least 20 times.
