Ushbu tezisda polimetilmetakrilat (PMMA) asosidagi qattiq polimer elektrolitlarda dielektrik relaksatsiya va ion o‘tkazuvchanlik jarayonlarining o‘zaro bog‘liqligi nazariy hamda ilmiy adabiyotlar asosida tahlil qilingan. Polimer matritsadagi zaryad tashuvchilarning harakatchanligi, ionlarning koordinatsion o‘zaro ta’siri, segmental relaksatsiya va fazalararo qutblanishning elektr transportiga ta’siri ko‘rib chiqilgan. Kompleks dielektrik singdiruvchanlik, elektr moduli va impedans spektroskopiyasi yordamida ion transporti mexanizmlarini baholash imkoniyatlari asoslangan.

В тезисе на основе теоретического анализа и научной литературы рассмотрена взаимосвязь диэлектрической релаксации и ионной проводимости в твёрдых полимерных электролитах на основе полиметилметакрилата (ПММА). Проанализировано влияние подвижности носителей заряда, координационных взаимодействий ионов, сегментальной релаксации полимерных цепей и межфазной поляризации на процессы электрического транспорта. Рассмотрены возможности исследования механизмов ионного переноса с использованием комплексной диэлектрической проницаемости, электрического модуля и импедансной спектроскопии.

This thesis presents a theoretical and literature-based analysis of the relationship between dielectric relaxation and ionic conductivity in poly(methyl methacrylate) (PMMA)-based solid polymer electrolytes. The effects of charge-carrier mobility, ion coordination, polymer-chain segmental relaxation, and interfacial polarization on electrical transport are discussed. The potential of complex dielectric permittivity, electric modulus formalism, and impedance spectroscopy for characterizing ionic transport mechanisms is examined. Particular attention is given to the relationship between relaxation dynamics and ionic conductivity and its significance for energy-storage applications.
