We proved that ferroelectric immersed in a liquid influences electric charge distribution at the surface. Therefore ferroelectric coating on bone implant surface promotes bone cell growth and proliferation, healing should be improved [1]. We synthesized ferroelectric BaTiO3 films on Ti and Ti39%Nb substrates by hydrothermal method [2, 3]. The bone cell growth is significantly higher on Ti39%Nb substrates coated by BaTiO3 than that on non-coated Ti39%Nb, glass and reference polystyrene [3].
