(a) The tensile moduli of PLGA, PHAa (the agglomerated nano-HA in PLGA composites) and PHAd (the well-dispersed nano-HA in PLGA composites). (b) The tensile strength at yield and the ultimate tensile strength (UTS) of PLGA, PHAa and PHAd. (c) The elongation (unitless) at yield and (d) the elongation at break of PLGA, PHAa and PHAd. (e) The compressive moduli of PLGA, PHAa, and PHAd. Values are mean ± SEM; n = 3; *p < 0.05 compared with PLGA; and **p < 0.05 compared with PHAa.
