摘要

In this work, the synthetic diamond nanoparticles are used as the non-ferroelectric fillers to obtain high pyroelectric performance in PVDF composite films. The oxygen-containing groups that inherently exist on the surface of the diamond nanoparticles make more content of PVDF transform from the alpha-phase to the beta-phase, contributing to the high pyroelectric coefficient. The 0.4 wt% diamond/PVDF film shows the highest pyroelectric coefficient of 870,000 mu C/cm(2)K, which is 3.5 times higher than the pristine PVDF. As a result, the diamond/PVDF films generate higher pyroelectric current and voltage than the pristine PVDF film. (C) 2020 Elsevier B.V. All rights reserved.
