In this presentation, discussion will be focused on enhancing the dielectric and mechanical properties of polyvinylidene fluoride (PVDF) and its copolymers via different strategies including interfacial chemistry and additives. The effect of different additives and interfacial chemical treatment on the dielectric breakdown strength, dielectric constant and loss factor is investigated. Systematic study is carried out towards achieving high dielectric constant while mitigating the possible reduction of dielectric breakdown strength. This is a highly desirable and relevant to important applications such as in actuators, capacitors and electric caloric devices. Another discussion is on an unusually large enhancement of PVDF film toughness and ductility using nanoparticles at very low concentration of 0.1%. Mechanistic explanations are also provided.
