Fig. (5).

SEM micrographs of HT63 composite before (A) and after (B) immerged in PBS pH 7.4 at 37 °C for 2 weeks. The image of T80 scaffold before soaking was similar to that revealed by the composite scaffold (A), thus was not shown here. The internal structure/ morphology of the submerged T80 showed increasing of porosity (C).
