Potential of Electrospun Poly(3-hydroxybutyrate)/Collagen Blends for Tissue Engineering Applications

Table 2

Thickness, porosity, and water contact angle (WCA) of the fibrous meshes as a function of the PHB/Coll ratio (mean ± SD; n = 3-4). For porosity, three values were calculated at different depths along the mesh thickness, corresponding to the surface (), middle (), and total porosity ().

PHB/Coll (w/w)	Thickness (μm)	(%)	(%)	(%)	WCA (°)
100/0	35 ± 1.7	84.3 ± 0.4	49.7 ± 1.6	17.2 ± 0.6	119.1 ± 10.2
70/30	50 ± 2.1^a	83.7 ± 0.2	52.2 ± 0.4^a	19.1 ± 0.7^a	32.9 ± 10.6^∗
