Synthesis and characterization of ZnO microrods with polyaniline prepared by hydrothermal method
In this study, polyaniline (PANI)-assisted zinc oxide (ZnO) growth were synthesized using low temperature hydrothermal method. Different concentrations of ZnO:PANI samples have been investigated. The structural and morphological analysis of the synthesized samples were carried out using SEM and XRD techniques. SEM images showed thin PANI layer and agglomerations formed on the rod's surface due to the polymerization of aniline and its interaction with ZnO. This thin PANI layer was more prominent at higher aniline concentration. XRD results revealed highly crystalline nature of the samples corresponding to the hexagonal wurtzite structure of ZnO. The length and width of the formed microrods in different concentrations were also calculated. The aspect ratio (L/W) of the samples showed a uniform trend as the concentration was increased. Further characterizations will be conducted in the future study of ZnO:PANI samples in order to understand its properties, which will be useful in the study of its photocatalytic activity and anticorrosive coating applications.
