摘要：

Fully functionalized nanophase polymers where high-dielectric-constant oligomers and electrically conductive oligomers are grafted to a dielectric elastomer backbone (see Figure) produce a significantly enhanced interface effect through exchange coupling. Consequently, they offer a high dielectric constant (close to 1000 at 20 Hz), an improved breakdown field and better mechanical properties, and a high electromechanical response.
