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