Влияние ионизирующего облучения и времени травления на низкотемпературную релаксацию в поливинилиденфториде

Влияние ионизирующего облучения и времени травления на низкотемпературную релаксацию в поливинилиденфториде

Abstract

В рамках настоящего исследования изучено релаксационное поведение полукристаллического полимера поливинилиденфторида (ПВДФ) с использованием метода термостимулированной деполяризации (ТСД). Экспериментальные измерения были выполнены на тонких пленках ПВДФ, подвергнутых облучению тяжелыми ионами Ne4+, Xe26+ и Bi52+ с энергиями около 1,2 МэВ/нуклон для Ne4+ и Xe26+ и примерно 3,1 МэВ/нуклон для Bi52+. Анализ полученных спектров ТСД выявил наличие трех основных релаксационных процессов при температурах около −45 °C, 20 °C и 40 °C. Установлено, что последующее химическое травление пленок приводит к возникновению нового релаксационного процесса при температуре около −10 °C, что может быть связано с появлением релаксаторов нового типа на поверхности треков.
