A thin‐film styrene polymer–carbon nanoparticle composite was obtained in a single‐stage alternating current dielectric barrier discharge plasma‐chemical process. The allotropic forms of the carbon nanoparticle filler were traced by transmission electron microscopy (TEM). TEM revealed an extraordinary adhesive encapsulation of the carbon nanoparticles by the polymer. It was found that the corona discharge regime provides an onion‐like carbon filler that enhances the mechanical strength and chemical resistance of the synthesized polymer–carbon nanoparticle film. Measurements of the electrical properties of the films implicitly confirmed the uniformity of the carbon filler distribution.

The polyaniline (PANI) films filled by carbon particles can demonstrate the conductivity increasing. The carbon particles uniform distribution in the PANI films can be received by their contemporaneously formation in the atmospheric pressure plasma. The films properties produced from aniline contemporaneously with carbon particles in the atmospheric pressure plasma are considered in that paper. The energy density threshold (~ 30 mJ/m) of gas discharge starting from which it is possible to obtain a continuous film filled with agglomerates of carbon particles was defined. It was showing that the such films has the amorphous morphology. It was defined that the carbon particles agglomerates in the PANI films. The carbon particles agglomerates concentration in the PANI films is about ~(4 – 7)·104 1/cm2 and slowly depends on the energy density. So the conductivity of that films cant be increasing by this particles. It was shown that the films moisture saturation is the main reason of them conductivity increasing. It was shown that the films creep are decreases and the hardness increases when the gas discharge energy density increases. Its because the crosslinks number is growth in the samples. The molecular weight of PANI films is low, so the Martens hardness value has low-level.

The influence of kinetic hydrate inhibitors on the process of natural gas hydrate nucleation was studied using the method of dielectric spectroscopy. The processes of gas hydrate formation and decomposition were monitored using the temperature dependence of the real component of the dielectric constant ε′(T). Analysis of the relaxation times τ and activation energy ΔE of the dielectric relaxation process revealed the inhibitor was involved in hydrogen bonding and the disruption of the local structures of water molecules.
