Abstract

Despite the unique switching characteristics of CO₂-responsive foaming, its stability remains questionable. In this protocol, we describe steps to synthesize a stable CO₂-responsive foam by adding the preferably selected hydrophilic nanoparticle N20 into the surfactant C₁₂A. We detail the selection of the most suitable nanoparticles for the surfactant by measuring the foaming volume and half-life of the dispersion. The protocol can be extended to manufacture with other types of responsive foams (e.g., light responsive foams, magnetic responsive foams). For complete details on the use and execution of this protocol, please refer to Li et al. (2022).¹.
