“…Therefore, there are polarisation phenomena associated to the rubber segments, the synergistic effect among the oxide particles added to the rubber formulation and between the interfacial polarisations at the NR/particles interfaces. 18 The real and imaginary parts of permittivity (ε' and ε'', respectively) diminish with frequency, thus reflecting the decrease of the interfacial polarisation between polymer amorphous chains and the oxide particles, as expected. A slightly decay of permittivity when decreasing particle size (i.e.…”

“…A typical formulation of vulcanized samples expressed as parts per hundred of rubber (in % phr, by mass) is as follows: zinc oxide (8.0), titanium dioxide (5.0), sulfur (6.0), accelerator (6.0), antioxidant (8.0), others fillers (7.0). Chemical composition in % phr is detailed in reference 18 .…”

“…A Phenix BK130/36 high voltage dielectric test set equipped with calibrated precision digital metering to fulfill the requirements of the IEC-60903 25 and ASTM D120-09 standards 26 was used for this purpose. In these assays, three test tube shaped rubber specimens (18 cm of height and 8 cm of diameter) were immersed in water tank and filled with water to a prescribed depth, according to the setup from reference 18 . The high-voltage electrode was inserted inside the sample specimens, whereas the grounding electrode was connected to the water in the tank outside the rubber sample.…”

“…17 Both metal oxides represent the most cost effective inorganic reinforcing fillers for the rubber industry over the past decades. Recently, we have reported that the introduction of nanofillers within the NR matrix, with well dispersed particles, is a good choice to enhance the dielectric properties in NR technology 18 . Therefore, it is important to highlight that in order to increase the dielectric properties homogeneous microstructures should be obtained.…”

The novelty of the present study relies on the straightforward sonication of ZnO and TiO 2 and incorporation to a complex formulation of latex, with other several organic-inorganic additives that influences the cross-linking reactions. The new elastomer with particles carefully sonicated exhibit improved electrical and mechanical properties. Strong interaction among the nanoparticles and the polymer amorphous phase has been proved by means of FTIR, SEM and XRD analyses. The synergistic effect of hybrid fillers with nanometric dimensions can be used to design high-performance natural rubber nanocomposites with enhanced electrical resistance and good cross-linking degree.

Dielectric elastomer actuators (DEAs) are one of the emerging areas of investigation in smart elastomer research and have attracted considerable interests due to their wide‐ranging applications, for instance in automation and soft robotic components. Commonly utilized dielectric elastomers (DEs) such as nitrile butadiene rubber (NBR) and its hydrogenated and carboxylated derivatives along with the dielectric fillers (titanium oxide, barium titanate, etc.) were considered to be one of the most established composite systems demonstrating high actuation performance. When subjected to external electrical field, the DEAs derived from the composites were, therefore, capable of reproducing high energy density and large deformation with fast response time. The recent research emphasizes that tunable material properties eventually triggered the improved actuation performance. The exploration of compliant electrodes fabricated by the conventional and state‐of‐the‐art lithographic methods was also crucial to improve actuation performance for the soft robotic applications. This review summarizes the commonly used DEs and dielectric fillers, their performances and challenges, and outlines the research progress (experimental and theoretical) in the field of actuators. Finally, a brief introduction to DEA‐based soft robotics application is also presented.
