In recent 20 years, electronic equipment has been developing rapidly in the direction of light, miniaturization, flexibility, and integration. It is urgent to meet the needs of matching energy supply system to solve the practical application requirements in the fields of intelligent communication and mobile medical treatment. Electroactive polymers (EAPs) are recommendable material for manifesting muscle-like actuation. The dielectric elastomers (DEs) obtained from the EAPs are quite capable of inducing electrical energy and transmute it into mechanical energy. DEs are capacitors covered by an outer elastic membrane, sandwiched between the two docile electrodes. In the beginning, for getting the efficient responses out of the DE actuators, the material requirements and electromechanical principal are applied. Viscoelastic damping, low dielectric loss, stretch ability, and dielectric permittivity are the desirable characteristics that we are expecting in a polymer. In the current research, we are going to adopt the sequential approach by describing the advances, challenges, and applications of DEAs in the coming future.

“…Due to the chemical bonding, van der Waals force, hydrogen bonding, electronic effects and surface effects among these functional groups, the dispersion of NDs in the PVA matrix is greatly affected, which also limits the application of NDs in various fields. 31 Therefore, it is of great significance to reduce the agglomeration and improve the dispersion of ND particles. 26 According to the literature, the traditional surface modification methods of nanodiamonds mainly include oxidation with air and ozone, carboxylation of NDs with strong oxidizing acid, and oxidation of NDs with hydrogen peroxide.…”

Summary Thermochemical heat storage materials offer high‐energy storage densities and clean means of long‐term solar energy storage. The aim of the study is to assess the potential heat storage efficiency of salt hydrates, based on sufficient hydration/dehydration performance, water sorption and cyclicability. MgSO4 7H2O, ZnSO4 7H2O and FeSO4 7H2O were evaluated based on preselected criteria. The main highlights of the dehydration result show that higher enthalpy was obtained for MgSO4 and ZnSO4, shows 2256 and 1731 J g−1 enthalpy, respectively. During hydration process, six water molecules were absorb by MgSO4 and ZnSO4 after pre‐dehydrated temperature 150°C and 120°C, respectively. The cycle stability of MgSO4 and ZnSO4 showed better performance which give rise 1210 g−1 and 1155 J g−1 enthalpy, respectively. It was expected that FeSO4 would show higher cyclicability due to their higher enthalpy (1400 J g−1) in the first round; however, overhydration does not permit it to released larger energy. The impact of relative humidity on water sorption performance and rate of hydration were reported which showed that MgSO4 and ZnSO4 can uptake maximum water under 85% and 75% relative humidity. Ongoing studies and the booming progress of ZnSO4 7H2O illustrate that likewise MgSO4 7H2O, it is also the potential candidate and can be use in thermochemical heat storage devices. To bring zinc sulfate heptahydrate into market, more detail studies in fields of evaluation of advanced materials and development of efficient and compact prototypes are still required.
