Special Issue Information

Dear Colleagues,

Nowadays, electronic devices are more demanding due to their excellent properties, including miniaturization, high-integration, and high intelligence. The traditional dielectric materials have difficulty in satisfying new requirements, including balanced dielectric properties and designability. Furthermore, there is a need to design electronic devices with high energy density and fast signal transmission. Therefore, materials with low heat dissipation and low dielectric properties are necessary to develop. The polymer dielectric properties mainly depend on the dielectric properties of the interfacial region.

This Special Issue will provide an international forum for researchers to discuss the most recent studies concerning the synthesis and dielectric properties of polymers and their composites. Both original contributions and reviews are welcome.

Elastomers, as a typical category of soft dielectrics, have shown great potential for developing stretchable electronics and soft transducers. However, the performance of dielectric elastomers (DEs) is susceptible to the dielectric permittivity of the material, whether as insulators or actuators. On the other hand, experiments suggest that the material viscoelasticity significantly influences the dielectric permittivity of DEs. Based on the theory of finite-deformation viscoelasticity, this work adopts the Brillouin function to develop a modeling framework to examine the effect of material viscoelasticity on the dielectric permittivity for the first time. A comparison of the data fitting results between the models with and without consideration of the material viscoelasticity is presented. Simulation results also reveal that the viscous network of the elastomer exerts a mitigation effect on the decrease in the dielectric permittivity when the material is deformed. Furthermore, it is found that the loading rate is a key parameter that strongly affects the dielectric permittivity, mainly through the inelastic deformation. Full article
