Abstract

ABSTRACT: Dielectric elastomer generators (DEGs) offer a solution for the growing sustainable energy needs. Despite the active research on DEGs, currently used materials do not possess the required properties to achieve the full potential performance of such generators, thus, limiting an economical attractiveness of DEGs. Therefore, tailor‐made materials for DEGs are in demand. Customizing the natural rubber recipe allows both dielectric and mechanical loss reduction, while the addition of nanodiamonds lowers the stress relaxation and hysteresis loss even further. The effect is most pronounced after chemical modification of nanodiamonds with silane coupling agents. Moreover, such modified nanodiamonds show less dielectric losses compared to unmodified nanodiamonds and allow reducing the dynamic loss tangent of the compound. © 2019 Wiley Periodicals, Inc. J.
