Ferroelectric polymer composites for capacitive energy storage

High dielectric constant polymer composites that can electrostatically store energy are widely used in advanced electronics and electrical power systems. Ferroelectric polymers are particularly attractive as matrices for dielectric polymer composites owing to their highest dielectric constant among the known polymers. To achieve high energy density, the dielectric constant and breakdown strength of the polymer composites need to be simultaneously enhanced. A variety of material structure design and processing strategies have been developed to increase the energy density of ferroelectric polymer composites. This chapter reviews the fundamentals and the recent developments in the design, synthesis, and characterization of ferroelectric polymer composites for capacitive energy storage applications.
