依据生物矿化的基本原理,通过仿生合成的方法,以聚丙烯酰胺作为基质合成了一种有机、无机复合的多孔碳酸钙材料。用X射线粉末衍射(XRD)分析、扫描电子显微镜(SEM)、傅里叶变换红外吸收光谱(FTIR)和电导率测定等手段对所得复合碳酸钙进行了表征,结果发现该多孔CaCO3晶体为方解石型,并且在结晶过程中,聚丙烯酰胺与CaCO3之间存在着相互作用,本文讨论了这种作用的可能机理。
Using biomimetic method, a kind of porous CaCO3 crystal with micrometer scale framework was synthesized in polypropyleneacylamide solution. The obtained CaCO3 crystals were characterized through Fourier transform infrared spectroscopy (FT-IR) ,X-ray powder diffraction analysis ( XRD), scanning electron microscopy (SEM) and conductance ratio analysis. The results showed that the framework of the CaCO3 was calcite. The interaction mechanism between CaCO3 crystals and polypropyleneacylamide was discussed.
