Morphology and microstructural characterization of MBG and the composite MBG scaffolds. SEM images of the surface (A) and cross-section (B) of MBGS. (C) TEM image of the MBG powder. (D) N₂ adsorption-desorption isotherms and pore size distribution curve (inset) of MBGS. (E) SAXRD and WAXRD (inset) patterns of MBGS. (F) SEM image of the cross-section of CBP/MBGS, the red arrow indicates the CDBGn/P(NIPAM-co-NMA) coating layer. (G, H) Typical stress-strain curves and average mechanical strengths of MBGS and CBP/MBGS. (I) Degradation curves of MBGS and CBP/MBGS incubated in PBS at 37 °C.
