摘　　要：围绕着分散相尺寸和两相界面粘接这两个关键问题 ,简单回顾了复合材料从熔融共混、聚合复合到纳米复合的发展历程。通过对具有重要理论意义和应用价值的聚合物 /层状硅酸盐 (PLS)纳米复合材料制备过程热力学驱动力的考察以及制备原理的分析 ,我们首次从理想状态下推导出了能在一定范围内预测聚合物相对分子质量与层状硅酸盐含量、层状硅酸盐片层间距与层状硅酸盐含量以及层状硅酸盐片层间距与聚合物相对分子质量关系的理论公式 ,并用文献中的实验数据进行了验证。Focused on two key factors of dispersion phase dimension and interface adhesion between two phases,the development course of polymer composites advancing from melt blending, polymerization composing to polymer nanocomposite is briefly reviewed.Based on investigations of thermodynamic driving force for preparation and its principles of polymer/layered silicate(PLS) nanocomposites which are not only important theoretical meaning but extensive application value, the relationships of layered silicate content,polymer matrix molecular weight and the interlayer distance of layered silicate are established under the ideal state theoretic formulae.The predictions of the theoretic formulae can well agree with the experimental data from reference paper[27] .
