“…Increasing the crosslinking temperature and, relatively, the composition hardening degree increases the wetting angle. e increase of the wetting angle at treatment temperature rise can be explained by the decrease in the composite surface energy, associated with the decrease in the active functional group concentration being in good agreement with the materials of paper [11].…”

It is determined that in order to create a protective coating with high physical, mechanical, and thermophysical characteristics, it is necessary to carry out the appropriate heat stepping during its formation. The relevance of such processing mode use providing the increase of physical-mechanical and operational characteristics of epoxy material coatings due to the structure-forming processes in the material is substantiated.

“…Carbon nanofillers, such as nanotubes, fullerenes, nanocarbon black, and graphene, are used to improve strength characteristics and prevent thermal destruction or to increase the temperature at which the combustion process occurs [16,18,[23][24][25][26]. The authors of [27][28][29][30][31][32][33] investigated the course of the process of thermal destruction of polymers. These provisions are consistent with the results of the research given in the work by authors [18][19][20][21][22][23][24][25][26][27].…”

This paper presents the technological aspects of increasing the thermal stability of polymers, with epoxy binder used to form the polymer materials. Polyethylene polyamine was used to crosslink the epoxy binder. To ensure the thermal stability of the polymer, nanodispersed condensed carbon with a dispersion of 10–16 nm was used. The research into nanocomposites under the influence of elevated temperatures was carried out using the “Thermoscan-2” derivatograph. Complex studies of thermophysical properties were carried out, according to the results of which the optimal content of nanofiller (0.050 pts.wt.) was determined. At the same time, this particular polymer was characterized by the following properties: temperature of the beginning of mass loss—T0 = 624.9 K; final temperature of mass loss—Tf = 718.7 K; relative mass loss—εm = 60.3%. Research into the activation energy of thermal destruction was performed to determine the resistance to the destruction of chemical bonds. It was proved that the maximum value of activation energy (170.1 kJ/mol) is characterized by nanocomposites with a content of nanodispersed condensed carbon of 0.050 pts.wt., which indicates the thermal stability of the polymer.

The experimental and theoretical investigations of mechanical properties of porous materials are one of the priority areas of development of condensed matter physics. Diatomite ceramics can serve as a raw material for structural heat and sound insulating materials and additives to some types of cement, as a polisher for metals and marble. Diatomite-based ceramics are also used for thermal insulation in aluminum production. The foamdiatomite ceramics is a promising porous material. But the properties of diatomite ceramics are not well studied, which determines the relevance of the study. The main task of the present work is the investigation of porosity and elastic moduli of diatomite ceramics, as well as the effect of thermal treatment on its physical-mechanical properties. The work deals with studying mechanical properties of porous ceramics based on diatomite – asedimentary rock composed predominantly of shells with micro- and nanopores of 50 to 500 µm. From the results of studying the microstructure of porous diatomite-based ceramics, the average porosity of samples (~50%) was determined, and the values of static (35 to 45 GP?) and dynamic (0.3 to 0.8 GP?) elastic moduli were experimentally measured. It was found that the values of elastic moduli decrease as material porosity increases. The experiment showed that the elastic modulus of the considered high-porous material was two orders of magnitude less than that of the crystalline one.
