Effect of the flow rate and air gap on fiber diameter of different materials. (A) Effect of the flow rate (0.05–1.2 mL/h) and air gap (25 and 28 cm) on fiber diameter of Alginate/PEO scaffolds prepared from 1% Alginate + 4% PEO solutions and the same scaffolds after alginate crosslinking and PEO removal; (B) Effect of the flow rate (1.5–4.5 mL/h) and air gap (18 and 25 cm) on fiber diameter of PCL and PCL/Alginate blended electrospun scaffolds (20% PCL, 20% PCL + 0.5% Alginate, 20% PCL + 1% Alginate); (C) effect of the flow rate (1.5–4.5 mL/h) and air gap (18 and 25 cm) on fiber diameter of PEOT/PBT and PEOT/PBT/Alginate blended electrospun scaffolds (14% PEOT/PBT, 14% PEOT/PBT + 0.5% Alginate, 14% PEOT/PBT + 1% Alginate).
