摘要: 利用生物矿化原理,以聚丙烯酸(PAA)作为有机基质,采用碳化法合成了具有枝状形貌的文石型碳酸钙粒子。通过场发射扫描电子显微镜(FESEM)、X射线衍射仪(XRD)和傅立叶红外光谱仪(FT-IR)等检测手段研究了产物的晶型及形貌,并初步探讨了粒子的生长机理。结果表明,在文石型碳酸钙粒子的合成中有机基质和反应温度是非常重要的参数。同时把该产品应用于聚氯乙烯(PVC)中,测定了塑料的力学性能和加工性能。这一研究将对碳酸钙形貌控制和性能改善起到一定的指导意义。

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.
