Abstract

There are few modeling papers on the mechanical behavior of halloysite nanotubes (HNT)-based system, which restrict the applications of these materials in advanced fields. In this paper, a model for tensile modulus of HNT-reinforced system is advanced based on Kolarik equation assuming the concentrations and moduli of dispersed HNT, networked HNT and interphase sections nearby the dispersed and networked HNT. The calculations of the advanced model at a number of levels of all factors are justified. Furthermore, numerous samples are used to confirm the forecasts of the established model by experimental data. The modulus of HNT-based system enhances by low HNT radius, high HNT length, high modulus of networked interphase section, high network modulus, low percolation onset, high modulus of interphase section around the dispersed HNT, great HNT modulus and high network percentage. The nonattendance of interphase section causes the nanocomposite’s modulus of 2.24 GPa, whereas the modulus of samples improves to 3.15 GPa by the interphase depth of 25 nm. Additionally, the experimental data of several samples containing different types of polymer media and HNT validate the predictability of the established model.

摘要

基于埃洛石纳米管（HNT）的系统力学行为的建模论文很少，这限制了这些材料在先进领域的应用。在本文中，假设分散的 HNT、网络化的 HNT 和靠近分散和网络化的 HNT 的界面部分的浓度和模量，基于 Kolarik 方程提出了 HNT 增强系统的拉伸模量模型。高级模型在所有因素的多个级别的计算都是合理的。此外，大量样本被用于通过实验数据确认所建立模型的预测。基于 HNT 的体系的模量通过低 HNT 半径、高 HNT 长度、网络化界面部分的高模量、高网络模量、低渗透起始、分散的 HNT 周围的界面部分的高模量而增强，高HNT模量和高网络百分比。界面部分的缺失导致纳米复合材料的模量为 2.24 GPa，而样品的模量通过 25 nm 的界面深度提高到 3.15 GPa。此外，包含不同类型聚合物介质和 HNT 的几个样品的实验数据验证了所建立模型的可预测性。
