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

摘要

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.
