DSC normalized thermograms of a PLLA sample electrospun at a traveling distance of 15 cm, a needle diameter of 0.50 mm, an applied voltage of 20 kV and a flow rate of 2 ml h⁻¹. Scan 1 is the first heating scan, scan 2 was recorded after heating the sample to 65 °C followed by cooling at 40 °C min⁻¹ to 20 °C, and scan 3 was performed after cooling the sample at 10 °C min⁻¹ from 200 °C to 20 °C.
