摘要:
The tetragonal barium titanate (BaTiO3) particles with novel shapes were synthesized by a surfactant-free hydrothermal method and fully characterized by Raman, XRD, SEM and contact angle analysis. The shape of particles are dependent on reaction temperature, pH value and mineralization time. The tetragonal BaTiO3 particles with different morphology possess different tetragonality, surface hydrophilicity and dielectric property, and so they exhibit distinct electric-field response. The high tetragonality and good dielectric property of the particles are proposed as a main power of enhancing the electric response of tetragonal BaTiO3 dispersed in hydrous elastomer.
