Description
Summary:The influence of temperature on the electrophysical characteristics of polymer composites based on a matrix of ethylene vinyl acetate filled with carbon black (CB) is investigated. It is established that the most noticeable transformation of the temperature dependences of the resistivity ρ( T ) after the first heating–cooling cycle occurs in composite samples saturated with peroxide. Saturation of the composite with peroxide and the crosslinking of macromolecules leads to the N-shaped character of the dependence ρ( T ). The occurrence of hysteresis ρ( T ) and its character indicate that in the studied composites, the process of crystallization of the polymer matrix has significantly less effect on the destruction of the conductive mesh formed as a result of agglomeration of CB particles compared with the processes accompanying melting.
