Degradation performance of RFP/PDLLA/nHA composite.

<p>A: Weight loss ratio in PBS; B: Variation in pH Values; C, D: ESEM micrograph showing degradation of two kinds of composites after 12 w in PBS; DF: degradation foraminulum, CHW: collapsed hole-wall. Each curve represents the mean ± standard deviation of 3 independent experiments performed in triplicate in A and B.
