Abstract
The article presents studies of nanomodified materials based on paraffin waxes with polyethylene as heat-storage materials. Accumulation of thermal energy is possible when converting electrical energy into thermal energy. In this case, the accumulation of thermal energy can occur as a central zone of nanomodified materials, and at its ends. This is due to the location of the electrodes in nanomodified materials. When CNT was mixed with polyethylene and the mixture was subsequently heated on the surface of a CNT, a homogeneous PE layer of a special structure was formed. The presented feature of the interaction can be considered as a special case of functionalization.
Highlights
The development and creation of nanostructured composite materials is currently one of the most urgent areas of scientific and applied research
Areas of application of such materials present fairly stringent requirements, which correspond to polymer composites, which have been actively studied in recent years [1, 2]
One way to increase the affinity of carbon nanostructures to modifiable matrices is functionalization through the formation of various types of surface groups, which contributes to a significant increase in the efficiency of nanomaterial use and a reduction in its expenditure norms [9]. Carbon nanotubes and their modifications act as nanomodifiers of various polymers, the performance characteristics of the resulting composites will depend on their properties and morphology
Summary
The development and creation of nanostructured composite materials is currently one of the most urgent areas of scientific and applied research. Experimental study of the features of the process of obtaining effective, selective catalysts for the synthesis of CNM by the thermal decomposition method will make it possible to carry out directed synthesis of a nanomodifier (with the required characteristics) for the polymers under consideration. Among the wide range of nanomaterials capable of increasing thermal conductivity, the following are distinguished: metal nanoparticles [10, 11], metal foams [12], carbon materials (fibers, nanotubes and graphenes) [14-17]. In these papers, the main attention is paid solely to the influence of nanomaterials or on the thermal conductivity or electrical conductivity, while the issues of heat release under the influence of electric current are not considered. The research tasks include research of heat release in a polymer composite based on paraffin and polyethylene modified with carbon nanotubes
