Abstract

The expanded Takayanagi model for a nanocomposite’s modulus after percolation onset is simplified and progressed for the strength of a halloysite nanotube (HNT)/polymer system by the nets of HNT and interphase after percolation onset. Many experimental records for various types of HNT-based samples are utilized to confirm the predictability of the progressed model. The HNT volume portion, interphase depth, HNT length, and network portion directly manipulate the strength of the system; however, percolation onset and HNT radius have adverse effects. A stiffer HNT network produces a higher strength for the system and the nanocomposite’s strength improves by 47% at the HNT network strength of 10 GPa. Also, the strength of the system develops by about 30% when the interphase network strength is 2100 MPa. Moreover, the nanocomposite’s strength is directly connected to the concentrations of the HNT and interphase networks. The approximations of the advanced model correctly fit to the experimental values of several examples. The progressed model also estimates the proper results for the characteristics of interphase and HNT/interphase networks in the samples. HNT-based nanocomposites can be applied in biomedical fields, such as bone tissue engineering and controlled drug release. © 2022, The Minerals, Metals & Materials Society.
