In this effort, the controllability of energy dissipation capability in nanocomposites via electrical signals, referred to herein as active damping, was studied. This mechanism benefits from the electrically conductive network of CNTs, as well as their high surface to volume ratio, to thermally enhance viscous phenomena, such as chain relaxation in polymers. For active damping, the thermomechanical response of the polymer is targeted and studied as a potential damping source within the nanocomposite. By taking advantage of the polymer relaxation resulting from an increase in temperature, the composite material shows controllable damping enhancement. However, the non-uniform temperature distribution in the composite sample has a large effect on the overall damping enhancement. The non-uniformity of the temperature distribution, both locally and globally, was studied via experiments and modeling to further shed light on this phenomenon.
