Abstract

ZnO-PAH composites were successfully synthesized using low temperature hydrothermal method. Poly(allylamine) hydrochloride (PAH) is usually layered with a negatively charged polymer to produce layer-by-layer film. No reports have investigated the effect of PAH directly on ZnO without the use of negatively charged polymer. The effect of varying PAH concentration on morphology and crystal structure of ZnO was determined using scanning electron microscopy (SEM) and x-ray diffraction (XRD) analysis, respectively. Fourier transform Infrared (FTIR) spectroscopy was also performed for all samples. SEM images revealed that Pure ZnO exhibits a smooth rod-like structures and rice grain-like structures for ZnO-PAH composites with varying PAH concentration. All peaks in the XRD spectra are indexed to the hexagonal wurtzite structure of ZnO and FTIR shown the presence of PAH polymer on the ZnO-PAH composites. Our results therefore suggest that PAH can be added to ZnO to form ZnO-PAH composites via hydrothermal method that have a significant effect on the morphology of ZnO microrods.
