Preliminary Study of Synthesis of Polyvinyl Alcohol (PVA) / Hydroxyapatite (HA) Composite Nanofiber with Electrospinning Technique
Journal Title: Invention Journal of Research Technology in Engineering & Management - Year 2019, Vol 3, Issue 2
Abstract
Polyvinyl alcohol (PVA)/hydroxyapatite (HAp) composite fiber is obtained using hydroxyapatite made from limestone. Fiber making is done by electrospinning technique using PVA solution with each HAp concentration of 1% and 5%. The polarization images microscope shows that the average diameter of the composite fiber PVA / HAp varies depending on the concentration of HAp in the solution and the voltage applied to electrospinning. At 1% HAp concentration with a voltage of 15kV, the average fiber size was 9.83 µm and with a voltage of 17kV, the average size of the fiber was 14.46 µm. Whereas at a voltage of 20 kV, fiber yield cannot be observed. At the 5% HAp concentration with 5kV the average fiber size was 10.45 µm, with a voltage of 15 kV, the average fiber size was 10.84 µm and with a voltage of 20 kV, the average fiber size was 11.9 µm. It can be concluded that the concentration of HAp and the magnitude of the voltage affect the size of the fiber produced. For this reason, it needs to be investigated further to obtain optimal conditions.
