Abstract
Effect of temperature on interfacial sliding in single‐walled carbon nanotube polycarbonate composites is investigated experimentally. We show that interfacial slip at the tube‐polymer interfaces can be activated at relatively low dynamic strain levels (∼0.35%) by raising temperature to ∼90°C. We attribute this to increased mobility of the polymer chain backbones at elevated temperatures and thermal relaxation of the radial compressive stresses at the tube‐polymer interfaces. These results show the potential of polymer nano‐composites as high temperature damping materials for vibration and acoustic suppression in a variety of dynamic systems.
