STRUCTURES OF HDPE/GaAs AND HDPE/GaAs<Te> COMPOSITES IRRADIATED WITH GAMMA QUANTA

Abstract

The results of optical studies of structural changes in composite HDPE/GaAs and HDPE/GaAs&lt;Te&gt; films irradiated with gamma quanta at doses of 100, 200, and 300 kGy at room temperature are presented. It was found that gamma irradiation of the initial polymer and their composite films leads to the formation of optical absorption bands at 220 and 280 nm, indicating the formation of C = 0 and C = C-bonds. It was established that composite HDPE/GaAs&lt;Te&gt; films are the most radiation-resistant in the absorbed dose range of 100…300 kGy.
