摘　　要：在提出纳米高岭土最小颗粒假设的基础上,通过对不同粒径的高岭土颗粒的晶胞数、总原子数以及表面羟基数的计算,讨论了它们与纳米级高岭土颗粒尺度大小的相关规律,并初步建立了相关模型。在上述基础上,将不同粒径的高岭土的阳离子交换容量实验结果与理论预测结果作了对比,结果表明,该模型可为纳米高岭土的表面处理研究提供指导。On a basis of the minimum dimension of nano-kaolinite particles supposed, through calculating the number of hydroxyl on the surface and atomicity of different granularities, the characteristics of them and the relationships between them and the surface specificities of nano-kaolinite particle were shown. At the same time, compared with experiment study, a model was built. The result shows that the model can indicate the surface modification study of nano- kaolinite.
