The compressive strength and modulus, and Vickers hardness of the scaffolds.
(a) Compressive strength and modulus; (b) Vickers hardness. *Represents significant difference (p < 0.05) and **represents very significant difference (p < 0.01) when the PLLA/BN/ZnO scaffolds, as compared to the PLLA, PLLA/BN-0.75 and PLLA/ZnO-5 scaffolds.
