Reversible CO<sub>2</sub>‑Responsive and Photopolymerizable Prepolymers for Stepwise Regulation on Demand

Abstract

CO<sub>2</sub>-responsive and photopolymerizable prepolymers are designed and synthesized. Their good photopolymerization kinetics and reversible CO<sub>2</sub> and N<sub>2</sub> responses to a bulk state and in a solution are reported. Stepwise modulation is verified in template imprinting. Results reveal that stable and high-resolution patterns can be produced by imprinting liquid prepolymers in CO<sub>2</sub> atmosphere, erased by warm heating, or retained permanently by chemical cross-linking through photopolymerization with the aid of a photoinitiator. By contrast, only blurry patterns are obtained in air
