Carbon dioxide (CO2)‐switchable composite nanogels consisting of biopolymer chitosan and synthetic polymer poly [N‐(3‐(dimethylamino) propyl) methacrylamide] are fabricated by soap‐free emulsion polymerization. Introduction of chitosan in nanogels remarkably enhances their CO2 sensitivity. Purging with CO2, the nanogel latex becomes clear gradually from the original creamy white. While purging with N2, the nanogel solution returns to the original latex state.
