Epoxies are important thermosetting polymers with exceptional features, which have been successfully employed for coatings. Polyester blends with epoxy enhances their chemical inertness, anti-rusting, toughness, strength, glass transition temperature, and heat stability, Epoxy/polyester blends have been further reinforced with nanocarbon, nanoclay, and inorganic nanoparticles to form nanocomposite coatings. Incorporating nanoparticles in epoxy/polyester has further improved their engineering properties. This review article principally offers state-of-the-art review of epoxy/polyester blends and epoxy-/polyester-based nanocomposite coatings. The epoxy/polyester and epoxy/polyester-based nanocomposites have been employed in non-flammable, anti-corrosion, anti-microbial, and anti-wear coatings in automotive, aerospace, energy, electronics, biomedical, and civil engineering applications. In order to fully utilize their potential, rigorous future attempts are needed for progress in the related technical fields.

“…Polymer composites containing electrically conductive filler have great potential for application in various fields, for example, for the creation of various sensors, antistatic shielding, and the protection against electromagnetic radiation, as well as it can be used in electronics and aerospace industry [2,3]. Carbon fillers, such as carbon nanotubes, fullerenes, graphene, carbon fibres, and activated carbon nanopowders, are often used for the fabrication of PCM with improved physical-mechanical [4][5][6] and electrically conductive properties [7][8][9]. Some authors note the prospect of using carbon black (CB) particles as filler for such materials [10][11][12].…”

The effect of carbon black (CB) nanopowder on the electrical properties of polymer composite systems based on the epoxy resin is investigated using the method of impedance spectroscopy. It is established that the electrical and dielectric properties of the studied systems significantly depend on the nanofiller content. It is found that electrical conductivity and dielectric constant exhibit percolation behavior when the filler’s content increases. In this case, the electrical conductivity increases exponentially, indicating the formation of filler electrically conductive mesh inside the polymer matrix. A small jump in electrical conductivity when reaching the percolation threshold indicates the formation of indirect contacts between the particles. The value of the percolation threshold of conductivity is 8%. It is shown that the dielectric constant of epoxy nanosystems is almost unchanged in the frequency range of 102–105 Hz. It is related to the structural features of the filler particles, which ensure the existence of a minimal dielectric gradient between the matrix and the filler. It is found that the dielectric constant of the studied systems also shows percolation behavior. The obtained material based on the epoxy matrix is characterized by a high value of dielectric constant, which at a carbon black nanopowder content of 29% is 4680. This material is characterized by relative frequency invariance and a high value of dielectric constant, so it has great potential for practical application.

The melting conditions of the electrode wires and the structure of coatings, obtained by the electric arc spraying method depending on the pressure of the spraying air flow, are analysed in the current paper. The effect of air pressure on the spraying angle of the flow of melted metal droplets is demonstrated. It is established that due to the decrease in this spraying angle, the temperature of the droplets increases. In addition, high-speed airflow is more easily captured by smaller molten metal droplets and during the contact with the substrate surface their deformations were more strongly. Due to such phenomenon, the porosity of the coatings was reduced and the number of lamellae, welded to each other, increased. With the increasing pressure of the air flow, the thicknesses of the lamellae were decreased, however, the amount of the oxide phase in the coatings has increased. As a result, the hardness, wear resistance and cohesive strength of the coatings, obtained at a higher pressure of the air flow, have increased, and the level of residual stresses of the first kind in them decreased.
