Preparation and Characterization of PAn-HPC/Fe3O4 and PAn-HPC/Fe2O3 Nanocomposite Using Hydroxypropylcellulose as a Steric Stabilizer

Nanocomposite of polyaniline containing Fe3O4 and Fe2O3 was synthesized by a chemical method using hydroxypropylcellulose as a steric stabilizer. The characteristics of product such as, morphology, conductivity, and particle size were studied. The results indicate that, these properties were dependent on the surfactant, amount and type of metallic oxide. When the concentration of Fe2O3 and Fe3O4 increased from 1 to 5 g/L, in PAn/Fe2O3 and PAn/Fe3O4 composites the conductivity decreased from 1.2 × 10−6 to 1.1 × 10−8 and 2.8 × 10−6 to 1.1 × 10−8S/cm, respectively, while the particle size of nanocomposite increased from 96 to 110, and 97 to 115 nm, respectively.
