The Fabrication and Characterization of PCL/Rice Husk Derived Bioactive Glass-Ceramic Composite Scaffolds
Figure 6
SEM micrographs and EDX spectra illustrating the change on the surface of the scaffolds after 14 and 21 days (left and right columns illustrate the images for 14 and 21 days, resp.) immersion in SBF (a-b) pure PCL scaffold (c-d) 10% (w/w) R-SBgC/PCL composite scaffold and (e-f) 20% R-SBgC/PCL scaffold and (g-h) 30% R-SBgC/PCL scaffold in magnification 1000x; marker 10 μm. The image in upper left of section (h) illustrates the small HA crystals with needles like structure on the surface of scaffold in higher magnification (10K X).
