In this paper, the “B” interphase parameter in the Pukanszky model and interphase strength for polymer carbon nanotube (CNT) nanocomposites are expressed by the critical interfacial shear strength (τ_c) and interfacial shear strength (τ) between a polymer matrix and CNTs. A suggested model and a developed Pukanszky model for tensile strength of nanocomposites are combined to develop the equations for “B” and interphase strength. Many experimental data for various samples confirm the models. The impacts of all parameters on the “B” and interphase strength are explained to approve the developed equations. The contour plots display the same trends for the roles of all parameters in the “B” and interphase strength. Low “τ_c”, high “τ”, thin and large CNTs as well as a dense interphase are ideal to obtain the high levels for “B” and interphase strength. Among the studied parameters, CNT size largely controls the “B” and interphase strength, while the waviness and strength of CNTs play insignificant roles.

聚合物基体和碳纳米管之间临界界面剪切强度对界面强度和 Pukanszky 的“B”界面参数的影响

在本文中，Pukanszky 模型中的“ B ”界面参数和聚合物碳纳米管 (CNT) 纳米复合材料的界面强度由聚合物基体和 CNT 之间的临界界面剪切强度 ( τ _c ) 和界面剪切强度 ( τ ) 表示. 将建议的模型和已开发的纳米复合材料拉伸强度的 Pukanszky 模型相结合，以开发“ B ”和相间强度的方程。各种样品的许多实验数据证实了这些模型。解释了所有参数对“ B ”和相间强度的影响，以批准所开发的方程。等高线图显示了“B ”和相间强度。低“ τ _c ”、高“ τ ”、薄而大的 CNT 以及致密的界面是获得高水平“ B ”和界面强度的理想选择。在所研究的参数中，碳纳米管尺寸在很大程度上控制了“ B ”和相间强度，而碳纳米管的波纹度和强度则起无关紧要的作用。
