Continuous Preparation of Core-Shell Capsules for CO۲ Detection UsingPhotosensitive Polymeric Resins

We report the development of CO۲ detector core-shell capsules with a novel production methodenabling low-cost, energy-efficient, and scalable manufacturing. The capsules consist of liquidcarbonate cores and highly permeable acrylated resin shells, produced through a continuous injectionmethod. These capsules exhibit rapid and controlled CO۲ uptake and release over repeated cycles dueto the high surface area and selectivity of the liquid sorbents. The capsules display a uniform sizedistribution, with a core diameter of ۲۹.۲-۰۹۱۳ mm and shell thickness of ۳۹۳.-۳۹۰۰ mm. Upon exposureto CO۲, the capsules undergo an absorption-desorption phenomenon, resulting in a color change fromblue to yellow within ۱۳۳ seconds, attributed to a pH change in the core due to CO۲ absorption.
