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.

“…The low surface area of g‐CN is also responsible for poor light absorption. Ample strategies have been adopted to boost the efficiency of g‐CN and to obtain better low‐cost heterogeneous photocatalysts, 11,12 including metal deposition, 13 texture engineering, 14–16 doping 17–21 etc. From 2009, the discovery of g‐CN with excellent visible light photocatalytic performance for hydrogen production has received increasing attention due to its non‐toxic, low‐cost and straightforward manufacture (e.g.…”

In this study, Fe2O3/graphitic carbon nitride (g‐CN) composites were fabricated using a simple calcination method. Iron chloride and urea were used as starting precursors for preparation of heterojunction composites (Fe2O3/g‐CN) by a quick stirring and calcination method. A sequence of Fe2O3/g‐CN composites were obtained by putting a specific amount of Fe2O3 on the surface of g‐CN at varied temperature (400, 450 and 500 °C). We accomplished a combined analysis using x‐ray diffraction (XRD), Fourier transform IR spectroscopy (FTIR), electron paramagnetic resonance (EPR), elemental analysis spectra (EAS), Brunauer–Emmett–Teller analysis (BET), diffuse reflectance spectra (DRS) and photoluminescence spectra (Pl) of resulting samples. Our findings demonstrate that Fe/CNx composites demonstrating a significant improvement in the separation of photogenerated carriers and hole formation, leading towards momentous photocatalytic activity. For the first time, the as‐synthesized composites were used for hydrogen production (water reduction) and methylene blue photodegradation under visible light illumination (λ = 420 nm). The superior sample Fe/CN450 exhibits an exceptional photocatalytic efficiency in both electron generation (hydrogen evolution rate) and hole formation (photodegradation) with a rate of 91.1% at 180 min. Along with this, Fe/CN450 has excellent photochemical stability in hydrogen evolution and pollutant removal. The potential photocatalytic mechanism of Fe/CN450 composite is compared with experimental results to characterize the photocatalytic phenomenon as a whole. © 2021 Society of Chemical Industry
