摘要：

The dendrite-shaped aragonite particles were 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 (FTIR). 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. The nano-CaCO3 was used in PVC and the mechanical and processing properties of the PVC were tested. In this paper, the industrial production of CaCO3 particles with exquisite and unique morphologies were prepared in the simple, low-cost and mild conditions.
