Abstract
Disclosed herein are polymeric compositions with low dielectric loss while maintaining high dielectric constant. The composition includes: a) at least one thermoplastic polymer; and b) graphite flakes that are coated with silica coating particles, wherein, the coated graphite flakes have a weight ratio of C:Si ranging from about 10:1-4:1, and the silica coating particles have an average diameter of about 80-400 nm.
