Abstract: Based on the basic principles of biomineralization,a novel aragonite calcium carbonate( CaCO3 ) compound material with a specific morphology was synthesized by biomimetic method under dynamic conditions. In our experiments, the glucan was used as the template. The obtained composite CaCO3 were characterized by using X-ray powder diffraction(XRD) analysis and scanning electron microscopy(SEM). Furthermore,according to the results of Fourier transform infrared spectroscopy(FTIR) and measurement of conductivity,the possible mechanism of supermolecule interaction between glucan and CaCO3 during the CaCO3 formation process was discussed.
