Electrospun Hydroxyapatite Containing Polyvinyl Alcohol Nanofibers Doped with Nanogold for Bone Tissue Engineering
Interceram 66 (2017) [3] 96-100
High-Performance Ceramics


Abstract:
Polyvinyl alcohol (PVA) was electrospun with addition of 5 mass-% nanohydroxyapatite (HA) powder doped with green synthesized gold nanoparticles (Au NPs). The biocomposite solution mixture was electrospun at a potential of about 20 kV. The results indicate that HA and Au NPs was uniformly distributed in the PVA nanofibers, which have diameter in the range of 100?150 nm for pure PVA and 300?400 nm with HA respectively. The thermal behavior of the composite was studied by TG and the morphology of the electrospun fibers were investigated by means of SEM technique. Tensile strength and elastic modulus confirmed that the mechanical characteristics of the PVA/HA nanofibrous mat were merely altered after Au additions. The formation of apatite like structure on fibers surface during the in-vitro test was confirmed by EDX analysis. The micro-porous fibers can have many potential uses in the repair and treatment of defected bone, and bone tissue engineering.
