Effect of polar particles on polymer composite dielectrics

Incorporated with polar ceramic particles, polymers were shown to exhibit improved dielectric properties. This work focused on the interaction of polar ceramic particles with the hosting polymers so as to improve the distribution of particles and the dielectric properties of polymer composites. Both computation and experimental observation were conducted toward the understanding of composite dielectric engineering. The electric field was found to be localized at the particle-polymer interface likely contributing to the polarization of polar particles.
