Abstract
Nano-Mg(OH)2 was synthesized by co- precipitation method. Peaks between 500 and 1250 cm− 1 in FTIR spectroscopy confirmed the presence of metal hydroxide stretching. TGA inferred that above 600° C, 50% of residue weight remained. HRTEM of nanocomposite gave an idea about the nonspherical morphology of particles of size 25 nm to 30 nm. SEM inferred that flower-like morphology for pristine Mg(OH)2 and higher % weight of aniline-intercalated Mg(OH)2 had agglomerated structure. UV visible spectrum inferred the presence of Mg2+ ion at 275 nm and the presence of amino-group-intercalated Mg(OH)2, which had a sharp peak at 193 nm and the intensity of which increases with the increase in % weight of aniline. PL inferred that aniline-intercalated Mg(OH)2 showed a lower intensity of which increased with higher wavelength value than the pristine and nanocomposite with PVA.
