Abstract
Polyvinyl alcohol (PVA)/Hydroxyapatite (HAp) composite nanofiber was obtained by electrospinning technique using a PVA polymer solution. Variations in the composition of PVA /HAp composite are (100: 0, 90:10, 85:15, 80:20, 75:25, 70: 30 %v). The PVA/HAp composite nanofiber was analyzed including nanostructure, porosity and tensile strength. The characterization of nanostructures using scanning electron microscopy (SEM) showed that the average diameter in the range of 173-234 nm, porosity in the range of 68-77%. The tensile strength test showed that the strain was in the range of 106.9 - 125.5% and tensile strength in the range of 9.77 - 15.85 MPa. This characteristic of PVA/HAp composite nanofiber can be applied as a scaffold in bone tissue engineering.
