“…Taking into account the reactivity of shungite, it can be observed that it is more reactive than coke and, at the same time, more resistant to the oxidation process than graphite. The composites based on ethylene propylene diene with an addition of shungite were synthesized by Barashkova et al [38]. Shungite was also introduced into nitriloacryl butadien rubber, ethylenepropylene rubber, butyl rubber, isoprene, and fluorine rubbers [39].…”

The aim of this work involved comparing the effect graphite and shungite have on the properties of dielectric elastomer-based materials. For this reason, dielectric elastomer–Sylgard (S) was filled with 1, 3, 5, 10, and 15 wt.% of graphite (G) and shungite (Sh). The structure of the obtained materials was studied by means of scanning electron microscopy and atomic force microscopy. The influence of the introduced additives on the thermal stability of the obtained composites was evaluated using thermogravimetry. Moreover, the mechanical properties and the dielectric constant of the elastomer with an addition of graphite and shungite were determined. Obtained results allowed us to establish that the presence of graphite as well as shungite significantly influences mechanical as well as dielectric properties. Additionally, the optimum mass of additives, allowing to increase the dielectric constant without the significant decrease of strain at break, was indicated. In the case of materials containing graphite, regardless of the filler content (1–15 wt.%), the mechanical as well as the dielectric properties are improved, while in the case of composites with an addition of shungite exceeding the 5 wt.% of filler content, a reduced tensile strength was observed.

In order to explain the time-temperature dependence of the electrical resistance of HDPE filled with carbon black, a model is proposed, in which an important role is played by the interfacial layer between the solid-phase filler and the polymer matrix. It is shown that the change in the structure of the macromolecules in the interfacial layer can be characterized using fractal concepts. The fractal dimension increases as the size of the filler particles decreases, and this is accompanied by a decrease in electrical resistance. During isothermal annealing treatment of the samples the fractal dimension of the interfacial layer is changed from 2.3 to 3. Correlations of the observed parameters are presented. The activation energy of increasing resistance in the initial period of the sample treatments is calculated. It is shown that the electrostatic field restrains the increase of the fractal dimension of the interfacial layer and the change in the resistance of the filled systems.
