Dielectric elastomer (DE) is a class of electro-driven flexible smart polymer materials, often using polyacrylate as an elastomer material. Unmodified acrylates typically have higher viscoelasticity and poor elasticity, resulting in slower response and less deformation during the elastomer process, resulting in higher driving voltages and less electrical strain. In this study, ZnO nanoparticles were added to polyacrylate (CN 9021NS) to study the effect of nanoparticles on the mechanical properties of composites, and the mechanism of ZnO nanoparticles on the improvement of composite properties was analyzed and elaborated. The results showed that the addition of ZnO nanoparticles could effectively improve the mechanical properties of elastic bodies. When the nano-ZnO particle content is 5 wt%, it has a lower Young's modulus (1.38 MPa), the highest elongation at break (115.72%) and a higher tensile strength (1.165 MPa).
