Work data for: "Optimization of Degrapol ® polymer electrospining conditions and their effect on fiber diameter"

This folder contains optimization of electrospinning parameters for Degrapol® polymer and their effect on fiber diameter. Degrapol ® is a biodegradable polyester–urethane composed of soft poly(ε-caprolactone-co-glycolide)-diol segments and hard poly(3-(R-hydroxybutyrate)-co-(ε-caprolactone))-diol segments and widely studied for tendon engineering. Both polymer components are biodegradable, and their degradation products are non-toxic. Degrapol® polymer dissolved in dichloromethane (DCM) and at concentrations of 15% and 20% (w/v), and in 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) at a concentration of 15% (w/v). Electrospinning was performed by systematically varying the processing parameters, including the applied voltage (13–20 kV) and the flow rate (0.1–0.7 mL/h). The needle gauge (22G) and the tip-to-collector distance (150 mm) were kept constant throughout the experiments. This dataset contains jet characteristics observed during electrospinning at various electrospinning conditions, microscopic images of fibers, and compare fiber diameter distribution graphs which are affected by voltage and flow rate alterations.
Moreover, mechanical features of two electrospun Degrapol® scaffolds with different fiber diameter were tested by uniaxial mechanical test and their ultimate tensile stress,
Young modulus, Yield strength, Yield strain, Elongation at break are given to understand the effect of diameter on mechanical features.
