EFFECT OF BLEND COMPOSITION AND UNIAXIAL ORIENTATION ON THE EVOLUTION OF STRUCTURAL HIERARCHY AND RESULTING DIELECTRIC PROPERTIES OF PET/PEI, NYLON 12 AND PEI FILMS
To meet the needs of the high-end electronics and energy industry, it is important to operate these devices in elevated temperatures and under high voltage. The dielectric materials for advanced capacitors must have high temperature tolerance (Tg>80C) high dielectric constant, low loss and high breakdown strength to meet the demands of the future. In order to understand fundamental relationships between the processing, structural hierarchy and electrical properties, in this dissertation we focus on slow crystallizing PET/PEI polymer blends, crystallizable Nylon 12 and noncrystallizable Polyetherimide and its chemical variants.
