Abstract

This article examined the impact of laser radiation on the dielectric properties of polymethylmethacrylate at frequency of 50 kHz within the temperature interval from 170 to 420 K. The authors showed that the processing of the samples with laser radiation leads to substantial changes in the dielectric constant and tangent of dielectric loss angle.

Highlights

The given paper presents us the results of the study of the dielectric relaxation processes in polymethylmethacrylate under laser irradiation at frequency of 50 kHz within the temperature interval from 170 to 420 K.The problem of studying the interaction of laser radiation with polymeric materials lies in the field of studying the impact of intense energy flows on the substance
