Predictions of micromechanics models for interfacial/interphase parameters in polymer/metal nanocomposites

In this paper, the polymer-metal interfacial/interphase parameters (PMIP) in polymer/metal nanocomposites are studied by modeling the mechanical properties. In this regard, the experimental results of yield strength, Young's modulus and elongation at break can be compared with the micromechanical models to evaluate the PMIP. The good agreement obtained between the experimental data of samples and the predictions confirms the applicability of models for polymer/metal nanocomposites. Many calculated parameters show the existence of a strong interphase in the reported samples. It is concluded that the fine morphology of nanoparticles and the strong interaction/adhesion at the polymer-metal interface can produce the significant PMIP in the polymer/metal nanocomposites.
