Abstract

Данная работа посвящена исследованию электрофизических свойств полиимидных пленок, их абсорбционных и частотных характеристик. Задачи, которые решались в ходе работы: 1. Экспериментальное изучение температурной зависимости проводимости 2. Расчет диэлектрических характеристик ε`(ώ), ε``(ώ) в области низких частот 3. Изучение температурных зависимостей коэффициентов абсорбции с использованием разных методов их определения 4. Анализ, полученных экспериментальных данных на основе эквивалентных схем замещения с использованием программного обеспечения MATLAB. В результате работы были исследованы электрофизические свойства полиимидных диэлектрических пленок и получена взаимосвязь этих свойств с жесткостью макромолекул.

This work is devoted to the study of the electrophysical properties of polyimide films, their absorption and frequency characteristics. Tasks that were solved during the work: 1. Experimental study of the temperature dependence of conductivity 2. Calculation of dielectric characteristics ε`(ώ), ε`(ώ) in the low frequency range 3. Study of temperature dependences of absorption coefficients using different methods of their determination 4. Analysis of the experimental data obtained on the basis of equivalent substitution schemes using MATLAB software. As a result of the work, the electrophysical properties of polyimide dielectric films were investigated and the relationship of these properties with the stiffness of macromolecules was obtained.
