All-organic dielectric-percolative three-component composite materials with high electromechanical response

An all-organic three-component dielectric-percolative composite with high dielectric constant was demonstrated. A two-component dielectric response was used as the matrix for the percolative composites, which consists of the PolyCuPc oligomer guest embedded in a polymer matrix host. It was found that the resulting three-component composites with the conductive polymer fillers in the dielectric composite host can be driven with a relatively high breakdown field. The results show that the composites exhibit enhanced dielectric and electromechanical responses.
