“…[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 properties of the composite are significantly influenced by the choice of the modification method of the polymer matrix, which is determined by the method of obtaining metal-filler particles (chemical, physical, electrochemical) [24][25][26][27] and the method of introducing the filler into the polymer matrix (synthesis of metal-filler particles in the polymer network, 28 synthesis of metal-filler particles during the formation of the polymer matrix, 29 mixing in the melt 18,30 and solution, 11 polymerization of the monomer in the presence of the metal particles 8,14 ).…”

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.
