STUDY OF ELECTRIC HEATING MODULES BASED ON CARBON NANOTUBES/POLYMER FOR AIR HEATING Shchegolkov A.V., Researcher, researcher-teacher, e-mail: alexxx5000@mail.ru Tulupov K.I., Student, e-mail: kostyatulupoff@yandex.ru Shchegolkov A.V., Ph.D. (Engineering), Associate Professor, e-mail: Energynano@yandex.ru Tambov State Technical University, 106/5, Building 2, Sovetskaya Str., Tambov, Russian Federation Abstract Energy-efficient electric heating technologies are associated with the use of new materials with the effect of temperature self-regulation. The use of polymer matrices and conductive additives is an effective approach for implementing the element base of heating materials. Polymeric materials have chemical resistance to changing operating conditions (corrosion resistance), high flexibility, which allows it to be used for heating complex objects, as well as the best combination of weight and size characteristics, allowing to create electric heating systems that expand the potential of electric heating systems. These and other advantages make polymer electric heaters attractive compared to metal and other existing analogues. In this work, heating polymer elements with the addition of carbon nanostructures (CNTs) for electric heating modules are obtained. For this purpose, the design of an electric heating module with three heating elements based on a modified CNTs polymer is developed. The heating dynamics of polymer elements is studied, and temperature fields are experimentally studied. Keywords Carbon nanostructures (CNTs), electric heating element, polymer matrix, electric heating system.
