摘要:High dielectric constant polymers find numerous advanced electrical applications such as pulsed power, power conditioning, gate dielectrics for field-effect transistors, electrocaloric cooling, and electromechanical actuation. Unfortunately, it is generally observed that higher polarization or dielectric constant tends to cause significantly enhanced dielectric loss. It is therefore highly desired that the fundamental physics of all types of polarization and loss mechanisms be thoroughly understood for dielectric polymers. In this talk, we intend to explore a new strategy of multilayer dielectrics for the purpose of high dielectric constant and low loss property. Effects of amorphous and crystalline dipoles, ionic polarization, interfacial polarization, and high temperature electronic conductivity will be discussed.
