Abstract:

BaTiO₃/polyurethane(BaTiO₃/PU)nanocomposite elastomers were prepared from barium titanate nanoparticles, polyester polyol, 2, 4-toluene diisocyanate, 1, 4-butanediol and 1, 1, 1-trimethanol propane by the one-step method.The density, hardness and dielectric constant of BaTiO₃/PU nanocomposite elastomers increased with the increase of the content of BaTiO₃ nanoparticles in nanocomposites.The electrostrictive properties of BaTiO₃/PU nanocomposite elastomers were investigated by the digital speckle correlation method(DSCM).It was found that through the on-and-off of the electric field, the electrostrictive strains of BaTiO₃/PU nanocomposite elastomers revealed corresponding shrinkage and recovery.The electrostrictive coefficient of BaTiO₃/PU nanocomposite elastomers was greater than that of the corresponding polyurethane elastomers, and the electrostrictive coefficient of composites decreased with the increase of the content of barium titanate nanoparticles.
