摘要
利用生物矿化原理,以聚丙烯酸(PAA)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.通过场发射扫描电镜(FESEM)、X射线衍射仪(XRD)和傅里叶变换红外光谱仪(FTIR)等检测手段研究了产物的结构和形貌,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.同时将该产品填充于聚氯乙烯(PVC)中,测定了PVC塑料的力学性能和加工性能.
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.
