Abstract: In the paper, the dendrite-shaped aragonite particles have been biomimetically synthesized through the carbonation route in the presence of polyacrylic acid (PAA). The as-prepared products were characterized with field emission scanning electron microscope (FESEM), X-ray diffraction (XRD) and fourier transform infrared spectroscopy (FT-IR). The effects of the reaction temperature and the concentration of PAA on the nucleation and growth of aragonite crystals were investigated. The possible growth mechanism of the dendrite-shaped aragonite particles was discussed. This research can open up a new avenue of industrial production of CaCO3 particles with exquisite and unique morphologies due to the preparation method employed by us is simple, low-cost and mild condition.
