Fig. 4From: Effect of sequential electrospinning and co-electrospinning on morphological and fluid mechanical wall properties of polycaprolactone and bovine gelatin scaffolds, for potential use in small diameter vascular graftsNormalized global frequency graphs of the fiber orientation. The fiber of sequential scaffolds shows multiple peaks of relative frequency, while in co-electrospun scaffolds predominant peaks are observed around 90 °, indicating a greater alignment. Where C0 is a sequential membrane and C1 is a co-electrospun membrane at 0.8 mL / h and B0 is a sequential membrane and B1 co-electrospun membrane at 1.2 mL / hBack to article page
