Effect of Iodine Doping on the Polyaniline /Clay Nano Composite Thin Films Prepared by Mechanochemical Intercalation Method

A mechanochemical approach is used to make a polyaniline:aicaulan clay nano composite in this study. the presence of a green color indicates the formation of polyaniline/clay. thin sheets of iodine-doped polyaniline/clay that have been pre-prepared are used. the weight percent of iodine in the nanocomposite films was 16%, 33%, and 50% wt percent of the total weight of pani/ clay. these as-deposited films were analyzed for physicochemical and optoelectronic features using fourier transform infrared (ftir) spectroscopy, scanning electron microscopy (sem), energy dispersive x-ray absorption spectra, and optical absorption spectra. ft-ir the chemical activity of both pure and iodine-doped thin polyaniline/clay sheets is then investigated using spectroscopic measurements.sem images reveal an uneven distribution of grains throughout the subsurface, according to morphological analysis. the optical band gaps of the films are then investigated using absorption spectrum measurements. indirect transitions’ energy transition gaps are characterized and determined. the energy band gap will be shown to vary depending on the content of polyaniline and clay iodine. as iodine concentration rises, the optical band gap decreases from 3.47to 2.18ev.
