“…The processes of modifying polymer materials with metal fillers of various natures are the subject of numerous studies, the result of which is the creation of new materials with unique properties for various fields of science and practice. [1][2][3][4][5][6][7] Obtaining metal-filled polymer composites with a wide range of technological and operational properties, their combination and predictable regulation become possible due to a number of factors. First of all, it is the presence of polymer matrices different in nature and, accordingly, in their characteristics (thermosets, 8,9 thermoplastics, 3,10 elastomers, 11,12 hydrogels 13,14 ) and metal fillers (metals, 8,15 noble metals, 16,17 ferromagnets, 18,19 metal alloys, 20,21 bimetals, 22 and hybrids 23 ).…”

The effect of the presence of finely dispersed metal fillers of various natures (Zn, Co, Ni) on the thermophysical characteristics (Vick heat resistance, glass transition temperature) of polyvinylpyrrolidone block copolymers with 2-hydroxyethylmethacrylate was studied. It was found that the heat resistance of the obtained composites significantly exceeds the heat resistance of unfilled copolymers and is in the range of 360-395K, depending on the nature and content of the metal filler. The change in heat resistance correlates with the change in glass transition temperature, which was evaluated according to the results of thermomechanical and dynamic mechanical thermal analyses. The results of this work are an additional source to characterize the structure of metal-filled copolymers: they confirm the participation of metal filler particles in the formation of the nodes of the copolymer spatial network, and also prove the formation of a different polymer network structure in the interfacial layer on the surface of the metal particle and in the polymer volume.

“…This approach ensures high values of conductivity of the composite at low filling degrees, especially when combining fusible systems and traditional conductive fillers [ 24 , 25 , 26 , 27 , 28 ]. These different technologies are aimed at obtaining materials with uniform distribution of metal in the polymer matrix, as well as obtaining metal filler of a particular dimension, which has a strong impact on the properties of the resulting composite [ 11 , 29 , 30 , 31 ].…”

The research studied the feasibility of using copper-coated polyethylene granules as a basis for creating efficient heat storage systems. A technology for imparting catalytic properties to a polymer surface by the joint processing of polymer granules and an activator metal in a ball mill with their subsequent metallization in a chemical reducing solution is proposed. The efficiency of copper-coating a polyethylene surface is shown to be largely determined by the activation stage and the assumption regarding the mechanism of interaction of the activator metal with the polymer surface is made. To obtain different amounts of metal on the polyethylene granules, it is proposed that the method of remetallization is used. It was established that the rate of copper ion reduction depends on the number of previous coatings and is determined by the area of interaction of the metal-coated granules with the chemical reducing solution. The obtained metal-coated polyethylene granules were characterized in terms of the viability of using it as a phase transition material for a heat storage system. Using the developed installation that simulates the heat accumulator operation, it was shown that the efficiency of using metal-coated polyethylene granules to create heat storage systems is higher. The copper coating deposited on the polyethylene granules was studied using scanning electron microscopy and X-ray diffraction analysis.
