Abstract
Copolymers of aniline and o-anthranilic acid (PANAA)/kaolinite clay composites were synthesized by 5:1 molar ratios of the respective monomers with different percentages of kaolinite clay particles via in situ chemical co-polymerization. The spectral characteristics of the resulting copolymers were investigated. The results were justified by measuring the UV-Vis absorption spectra, FT-IR for PANAA copolymer, and the in situ PANAA/kaolinite clay composite. The thermal gravimetric analysis for the isolated copolymer powder in absence and in presence of kaolinite clay was carried out. Moreover, the morphology of the polymer clay composites system was studied by the scanning electron microscope micrographs at different magnifications. X-ray diffraction was used to measure the nature of the copolymer and extent of crystallinity present in the neat copolymer and copolymer/kaolinite composite materials.
