Abstract In this study, the conventional Chow model for the tensile modulus of polymer composites containing fully aligned particles is simplified and developed for polymer nanocomposites, taking into account the effects of interphase and particle arrangement. The results obtained from the developed model are compared to the experimental results of several samples containing spherical, layered, and cylindrical nanoparticles. The predictions of the developed model are in good agreement with the experimental data, whereas the calculations of the original model deviate. The moduli of nanocomposites reinforced with spherical nanoparticles depend on the properties of the interphase alone. Additionally, a low volume fraction of the interphase eliminates the effect of matrix Poisson’s ratio on the moduli of nanocomposites containing layered and cylindrical nanofillers. These results demonstrate the important role of the interphase in the mechanical behavior of polymer nanocomposites.

假定相间区域和颗粒排列的聚合物纳米复合材料拉伸模量的 Chow 模型的发展

摘要 在本研究中，考虑了界面相和颗粒排列的影响，简化和开发了聚合物纳米复合材料的包含完全排列的颗粒的聚合物复合材料的拉伸模量的常规 Chow 模型。从开发的模型中获得的结果与包含球形、层状和圆柱形纳米粒子的几个样品的实验结果进行了比较。所开发模型的预测与实验数据非常吻合，而原始模型的计算结果存在偏差。用球形纳米粒子增强的纳米复合材料的模量仅取决于中间相的性质。此外，较低的界面体积分数消除了基质泊松比对包含层状和圆柱形纳米填料的纳米复合材料模量的影响。这些结果证明了界面在聚合物纳米复合材料的力学行为中的重要作用。
