Fig. 6

Contour plots of Young’s modulus (MPa) of electrospun PCL fibers as a function of H-PCL fraction, fiber diameter, stress at break, and strain at break. (a–d) Oriented fibers; (e–h) random fibers. Panels show: (a, e) diameter vs. H-PCL fraction; (b, f) stress at break vs. H-PCL fraction; (c, g) strain at break vs. H-PCL fraction; and (d, h) stress vs. strain at break. Black dots represent experimental data.
