Abstract: 

The paper presents a new approach to the development of polymeric materials modified by intrinsic and extrinsic semiconductors to enhance energy capacity. The analysis of the problem was done. It is shown that an increase in the thermal conductivity of a polymeric material can significantly increase the service life of metal-polymer friction couples. It has been established that the introduction of semiconductors into the tribological contact can significantly change the process of friction. For testing, horizontal and vertical holes were drilled into the polymer material. Heat-conducting tubes made of copper were inserted into the holes, which, in turn, were filled with electron-type and hole-type conductivity semiconductors. Depending on the combination of the polymer and a type of semiconductor conductivity, such a tube can operate in the mode of a microthermoelectric cooler, a microthermoelectric generator or diodes, while reducing the energy income to the metal counterpart.

Keywords: 
polymer, metallic friction element, n- and a-type semiconductors, electric and thermal field.
