Polyvinylidene fluoride/hydroxyapatite/beta-tricalcium phosphate multifunctional biocomposite: Potentialities for bone tissue engineering
Bioactive ferroelectric composites based on polyvinylidene fluoride, hydroxyapatite and beta-tricalcium phosphate have been synthesized and their structural, microstructural, bioactive, and ferroelectric properties are characterized. Structural and FTIR investigations showed the presence of the polar polyvinylidene fluoride (beta(2)) phase, while ferroelectric characterizations revealed remnant polarizations and coercive field, around 0.04 mu C/cm(2) and 28 kV/cm, respectively, for these biocompatible samples. Structural and microstructural analysis of samples previously immersed in simulated body fluid for 7 days revealed a large apatite phase growth (1.45 mu m) on the composites' surfaces as a strong indication of their elevated bioactivity and potentialities for bone tissue engineering.(C) 2017 Elsevier B.V.
