摘要：

通过沉淀反应法，以有机质十八碳醇磷酸酯（ODP）作为添加剂，制备了一种新型的自组装片状纳米碳酸钙材料。所得产品通过X射线衍射（XRD）、场发射扫描电镜（FESEM）、傅里叶红外光谱（FTIR）、热重分析（TGA）、活化度和接触角等测试手段对其结构和性能进行了表征。实验结果表明，当ODP添加量为2.0%时，碳酸钙活化度可达到99.9%，接触角为123.8°，具有较好的疏水性。所以ODP的加入不仅可改变碳酸钙粒子的形貌，而且在碳酸钙晶体的结构和性能等方面起着重要调控作用。

Abstract:

Exquisite and unusual plate-shaped nanometer CaCO₃ particles were successfully preparated through a facile precipitation reaction of Na₂CO₃ with CaCl₂ in the presence of octadecyl dihydrogen phosphate（ODP）. The hydrophobic property of CaCO₃ was revealed by active ratio and the contact angle tests. The products were characterized through a transmission electron microscope（FESEM），X ray diffraction（XRD），Fourier transform infrared spectroscopy（FTIR）and thermogravimetric analysis（TGA）. With 2.0% of ODP dosage，highly hydrophobic CaCO₃ was obtained with active ratio of 99.9% and contact angle of 123.8°. The experimental results revealed that the addition of ODP had an effect on the control of morphology，structure and properties of CaCO₃.
