Abstract
Polyaniline composite and nanocomposite were generated in aqueous and aqueous/nonaqueous media by using ammonium peroxydisulfate as an oxidant in the presence of various surfactants such as sodium dodecylbenzenesulfonate, poly(vinyl alcohol), hydroxypropylcellulose, poly(ethylene glycol), and poly(vinyl pyrrolidone). The results indicated that the morphology and size of the particles were dependent on the type of surfactant and solution used. The size range of the particles and nanoparticles was about 75–160 nm. The molecular structure was studied by using Fourier‐transform infrared spectroscopy,and the results showed that the intensities of the peaks were dependent on the nature of the surfactant. J.
