Abstract:In this paper, a biobased ternary composite microgel (CS-DP-AA) was designed and prepared, which was based on chitosan and had a reversible response to CO 2 . The synthesis of CS-DP-AA microgel was proved by infrared spectroscopy, chromatography−mass spectrometry, X-ray photoelectron spectroscopy, and Raman spectroscopy. The structure and properties of CS-DP-AA microgel before and after CO 2 response were characterized by scanning electron microscope, transmission electron microscope, ultraviolet visible spect… Show more
