“…Therefore, it only showed a slight shoulder peak at approximately 18°, indicating that the PEICT nanofiber is amorphous. On the other hand, the XRD pattern of the ZnO nanoparticle sample exhibited clear crystalline peaks at 2θ values of 31.76°, 34.51°, 36.33°, 47.69°, 56.86°, 63.10°, 66.68°, 68.22°, and 69.32°, which correspond to the (100), (002), (101), (102), (110), (103), (200), (112), and (201) planes of the hexagonal wurtzite structure of ZnO [ 31 ]. It was found that there was no significant shift in the peak position of ZnO upon the adsorption on the PEICT nanofiber surface, indicating that the ZnO nanoparticles were not only well-distributed in the PEICT nanofiber mat, but the crystal structure of the ZnO nanoparticle was also preserved during nanoparticle loading by the immersion process with post-electrospinning solvent treatment.…”
