Abstract Scope |
Polymer self-healing mechanisms have allowed new routes to mitigate micro and macro-scale damage in composites. Carbon nanotube (CNT) or other conductive nanoparticles can be loaded in these polymers to enhance their electrical and thermal conductivities for multi-functional applications. The influence of nanotubes on self-healing properties are yet unknown. In this work, the effect of CNT loading on the self-healing properties of the self-healing polymer-based nanocomposites are studied via molecular dynamics simulations. DGEBA based vitrimer is considered as the polymer system and loaded with single-walled CNTs. A temperature-dependent self-healing (reversible bond reaction) model was developed in molecular dynamics simulations using a cut-off-based bond formation algorithm. The mechanical properties were assessed for the CNT loaded self-healing polymers with respect to the pristine and unloaded host polymer system. The results from the atomistic studies give insights into the design of the optimum properties of self-healing polymer nanocomposites for multifunctional applications. |
