Material characterization. (a) Crystallinity of the materials after 0, 1, 2, 3, and 4 weeks of hydrolysis. (b) Inherent viscosity after 0, 1, 2, 3, and 4 weeks of hydrolysis; n = 1‐2. (c) Toughness of the materials after 0, 1, 2, 3, and 4 weeks of hydrolysis; n = 3–5. (d) Strain at break after 0, 1, 2, 3, and 4 weeks of hydrolysis; n = 4‐5. p < 0.05 between the indicated material (∗) and PLA at the same time point.
