An electroactive polymer nanocomposite, in which high dielectric constant copper phthalocyanine oligomer (o-CuPc) nanoparticles are incorporated into the block polyurethane (PU) matrix by the combination of "top down" and "bottom up" approaches, was realized. Such an approach enables the nanocomposite to exhibit colossal dielectric and electromechanical responses with very low volume fraction of the high dielectric constant o-CuPc nanofillers (∼3.5%) in the composite. In contrast, a simple blend of o-CuPc and PU composite with much higher o-CuPc content (∼16% of o-CuPc) shows much lower dielectric and electromechanical responses.
