Supercritical CO2 was used to produce CaCO3 thin films on biopolymers such as cellulose and chitosan coated on glass substrates from aqueous solutions of calcium acetate and poly( acrylic acid) (PAA). The scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy-dispersive X-ray (EDX) results suggest that nucleation occurred throughout the biopolymer matrix, followed by crystal growth into vaterite particles. This methodology is a promising process for the fixation of CO2 and utilization of biomass.
