Purpose. To predict the functional characteristics of a polymer-BNT type system, and then create new multifunctional nanocomposite polymer materials containing carbon nanotubes of different sizes and modifications, with specified and controllable properties.
Application area. New substances and materials.
Advantages. There are no analogues in Ukraine.
Description. As a result of the studies, the influence of various factors on the distribution and aggregation of carbon nanotubes in the polymer matrix, as well as the formation of a percolation cluster, was established. A number of stabilized samples of carbon nanotubes were obtained using different stabilizers. Technological modes have been developed that make it possible to specifically regulate the distribution of filler particles.
A series of composite materials were produced using a piston extruder, their microstructure and functional characteristics were studied using methods of optical microscopy, thermophysical, electrical and mechanical analysis.
A number of nanocomposite polymer materials containing carbon nanotubes with improved functional characteristics have been obtained. Based on their functional characteristics, the obtained materials are promising for creating filaments for 3D printing based on them.
The approach to mathematical modeling and description of the percolation behavior of thermal and electrical conductivity of polymer-VNT systems has been improved, in particular modeling that takes into account contributions from the surface layer between the matrix and the filler, as well as modeling the effects of charge tunneling. In the future, the proposed mathematical models will make it possible to predict the functional characteristics of a polymer-BNT type system, and then create new multifunctional nanocomposite polymer materials containing carbon nanotubes of different sizes and modifications, with specified and controllable properties.
