Limited equations for determining the mechanical performance of Halloysite nanotubes (Hal)/polymer samples ignore the reinforcing efficacy of the interphase zone. The Kolarik system and Pukanszky model are used to determine the tensile strength of Hal-reinforced nanocomposites, and developed models are validated with experimental data and parametric inspections. Interphase properties, Hal content, and interphase thickness directly influence the nanocomposite's strength.
There are limited equations for determining the mechanical performance of halloysite nanotubes (Hal)/polymer samples, and these equations ignore the reinforcing efficacy of the interphase zone. In this article, the Kolarik system is used to determine the tensile strength of Hal-reinforced nanocomposites by Hal size, Hal concentration, and interphase properties. In addition, Pukanszky model is modified for this material type to account for effective Hal concentration based on the advanced Kolarik model. Numerous sets of experimental data for several samples and parametric inspections endorse the developed models. Both interphase depth and power directly govern the nanocomposite's strength and the interphase factor A in the advanced Kolarik model. The lowest ranges of interphase properties lead to the lowest level of A, and at this level, there is no strengthening of the nanocomposites. The Hal radius (R) of 10 nm and Hal length (l) of 3 mu m lead to the highest A of 50 and the maximum relative strength of 4.5 (350% improvement in nanocomposite's strength), whereas Hal with R > 50 nm and l < 1.5 mu m cannot reinforce the sample. Moreover, the Hal content, interphase parameter B, and interphase thickness have a direct relationship with nanocomposite's strength according to the developed Pukanszky model, whereas the Hal radius has an inverse relationship.
