Over the past 15 years, researchers have discussed the investigation of self-assembled gels and CO2-responsive gels in a range of novel applications. As carbon dioxide is readily available, affordable, and fails to accumulate up within the system, using it as a stimulus-responsive material offers a lot of potential. Many CO2-responsive materials have been explored earlier, encompassing polymers, latex, surfactants, and catalysts. As a subset of CO2-responsive polymers, the study of CO2-responsive gels (insoluble, cross-linked polymers) is a distinct topic since CO2 induces a number of unique changes in the gel, Such as swelling or distorted shape. Subsequently, Queen's University researcher Philip Jessop investigated across CO2-responsive gels.
Key Explored Concepts:
Controlled flow (fluid) via CO2-triggered aggregation and its reversible CO2 absorption-desorption capacity are two of its most extensively investigated qualities and are used in CO2 mothballing and enhanced oil recovery (EOR).
These CO2-responsive gels were broadly categorized by particle size into nanogels, microgels, aerogels, and big gels. The authors evaluated the manufacture, characteristics, and uses of these CO2-responsive gels. The scientists also carried out a review research on poly(ionic liquid) gels that undergo CO2-induced self-assembly.
