The establishment of interphase region around nanoparticles accelerates the percolating of carbon nanotubes (CNT) in polymer nanocomposites reinforced with CNT (PCNT), due to the linking productivity of interphase district before the physical connecting of nanoparticles. Therefore, the interphase is an important character in the networks of CNT in PCNT. Here, a simulation study is presented to investigate the interphase connection in the mechanical possessions of PCNT including tensile modulus and strength. A number of models comprising Takayanagi, Ouali, Pukanszky and Callister are developed by the assumption of an interphase district in the CNT excluded volume. The advanced models depict the optimistic influences of reedy and lengthy CNT besides dense interphase on the stiffness and tensile power of nanocomposites. The Pukanszky calculations depict that the interphase strength plays a more noteworthy role in the nanocomposites strength compared to the CNT length.
纳米粒子周围相间区域的形成加速了碳纳米管增强聚合物纳米复合材料(PCNT)中碳纳米管(CNT)的渗滤,这是因为在纳米粒子物理连接之前相间区域的连接效率较高。因此,相间是PCNT中CNT网络的一个重要特征。在此,我们进行了一项模拟研究,以探究相间连接对PCNT力学性能(包括拉伸模量和强度)的影响。通过假设CNT排除体积中的相间区域,开发了包括Takayanagi、Ouali、Pukanszky和Callister在内的多种模型。这些先进模型描述了粗糙且长的CNT以及致密相间对纳米复合材料刚度和拉伸强度的积极影响。Pukanszky的计算结果表明,与CNT长度相比,相间强度在纳米复合材料强度中发挥着更显著的作用。
