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 (P₁), middle (P₂), and total porosity (P₃).
