Nanosized Fe(OH)(2) was synthesized by a coprecipitation method. Peaks between 500 and 1250 cm(-1) in Fourier transform infrared (FTIR) spectroscopy confirmed the presence of metal hydroxide stretching. X-ray diffraction showed the suppressed crystalline system of Fe(OH)(2)/aniline (ANT) due to the presence of a higher weight percentage of the dispersing agent, ANT. Thermogravimetric analysis implied that 75.5 wt % of residue remained up to 800 degrees C. High resolution transmission electron microscope (HRTEM) analysis of Fe(OH)(2)/ANI revealed that its size ranged from 10 to 50 nm with a rodlike morphology. Scanning electron microscopy implied that pristine Fe(OH)(2) had a nanotriangular platelet morphology, and a higher weight percentage of dispersing agent intercalated with Fe(OH)(2) had a spheroid with an agglomerated structure. The (UV-visible) spectrum implied the presence of Fe2+ ions at 326 nm and the existence of an amino group intercalated with Fe(OH)(2) showed a sharp peak at 195 nm, the intensity of which increased with increasing intercalated dispersing agent weight percentage. Photoluminescence showed that ANI-intercalated Fe(OH)(2) showed a lesser intensity than the pristine Fe(OH)(2). (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 118: 1728-1737, 2010
