Abstract
ZnO–polyaniline (PAni) nanocomposites were fabricated through a chemical method using Zinc acetate hexahydrate, ammonium hydroxide and different ratios (5, 15, 20 wt %) polyaniline. The FESEM images of the nanocomposites revealed that ZnO-PAni nanocomposites have a twin-prism structure. The XRD analysis has shown the hexagonal wurtzite structure of ZnO. Presence of P Ani did not cause any change in crystal structure of ZnO. Results of UV–Vis spectra indicate that the ZnO-PAni nanocomposites absorbed visible and ultraviolet light. This may be may be one of the interesting qualities of the prepared ZnO-PAni nanocomposites. Remarkable changes in the properties of the composites were observed, which are due to the interfacial interactions between ZnO and PAni, The interactions caused by hydrogen linkages and surface effects were observed by Raman spectrum analyses.
