Composite preparation
The polymer solution was prepared by dissolving different
ratios 90:10, 80:20, 70:30, 60:40 of PVA/IGT in 100 ml of deionized
water. We selected an 80:20 ratio of PVA/IGT, as it obtained
a maximum solubility in comparison with other solvents used for
electrospinning. The NC in different concentrations, 0.0%, 1%, and
3% (w/w), was used. The effect of NC on the nanobiopolymers was
investigated by FTIR analysis. The homogenized NC was then slowly
added to the PVA/IGT solution with stirring process at room temperature.
The solution was allowed to stir for 30 min in a sealed
container and the obtainedmixture was further sonicated for 5 min.
