Abstract
Researchers are devoted to developing dielectric elastomers (DEs) with excellent electromechanical properties as an artificial muscle material. The authors report a new class of semi-interpenetrating network (semi-IPN) composites that contains siloxane-modified linear polyurethane (PU) and silicone rubber through reasonable design of polymer structure. The organic-filler copper phthalocyanine (CuPc) is chemically grafted into the semi-interpenetrating network as a cross-linking point and exhibits excellent dispersibility in the matrix. The various properties of the obtained composite films are also evaluated. The dielectric constant (8.65 at 1 kHz) and maximum actuation strain at 30 MV m−1 (5.32%) are significantly higher than those of semi-IPN composites.
