Iranian Gum Tragacanth (IGT) is among the most natural polymers which has interesting properties such
as nontoxic nature, biodegradability and high resistance to bacterial attacks making it applicable for
tissue scaffolds, protective clothing, and wound healing. In the current work, polyvinyl alcohol (PVA)/IGT
nanocomposite fibre is prepared by using the electrospinning (ELS) technique in an aqueous solution
with different volume ratios of 60/40, 70/30, 80/20, and 90/10. To enhance the chemical and mechanical
stability of the produced samples, different amounts of nanoclay powder (1% and 3%) are added also to
the solution. The blended nanofibres are characterized by scanning electron microscopy (SEM), Fouriertransform
infrared (FTIR), and bioactivity evaluation in phosphate buffered saline (PBS) and simulated
body fluid (SBF) solutions. The FTIR analysis indicated that PVA and IGT may have H+ bonding interactions.
The results revealed that with a higher amount of IGT, a superior degradation as well as a higher chemical
and biological stability could be obtained in the nanobiocomposite blend fibres. Furthermore, the blend
nanofibre samples of 80/20 and 3% nanoclay powder exhibit a significantimprovement during evaluation
of its properties
