Abstract

In this work, the features of the dependence of radiothermoluminescence (RTL), charge stabilization, change of the temperature of structural β-and γ-transitions on the dose of γ-irradiation and degree of filling Φ of composites based on high-density polyethylene (HDPE) and piezoceramic fillers of the PKR-3M type are investigated. It is shown that the dependences of thermoluminescence intensity of the filling degree J(Φ) are characterized by extrema at the filler content as high as 5 vol % and a dose D = 20−30 kGy. It is shown that γadiation at defined doses leads to inhibition of the process of β-relaxation of HDPE in the composition, which can be associated with the formation of new trapping centers of excess charges of electrets.
