Figure 2

Chemical and physical characterization of fibrous composite scaffolds. (a) Fourier transformer infrared spectroscopy (FTIR) spectra of the tested fibers. The inset within the graph highlights the carbonyl stretching peaks. (b) Wide-angle X-ray diffraction (WAXD) showing the effect of the ZnO nanoparticles on the carrier polymer (PCL) (110) and (200) crystal planes. The inset demonstrates that the incorporation of ZnO induces narrowing of the crystal planes, correlating with an enhanced crystallization, compared to the control (purple). (c) Two-dimensional WAXD images show the effect of ZnO nanoparticles on the reflection banding arc’s annotated within with arrows.
