文摘
- •
The aligned porous structure of HA/BaTiO3 composite was similar to the lamellar Haversian system in bone tissue.
- •
The piezoelectric d33 coefficient of HA/BaTiO3 with porosity of 50% was 5.0 pC/N, much higher than that of natural bone.
- •
HA/BaTiO3 with porosity of 50% promoted proliferation, differentiation and adhesion of MG63 cells remarkably.
