Fabrication, Thermal, and Magnetic Properties of Fe₂TiO₅/Polyaniline Nanocomposites

Abstract

Polyaniline-iron titanate nanocomposites (NCs) with two contents loading of Fe₂TiO₅ were successfully synthesized by sol-gel technique. FTIR, XRD, SEM, STA, and VSM were used to characterize the structure and properties of the obtained NCs. The results indicated that Fe₂TiO₅ NPs with particle size between 25 and 75 nm were distributed in PANI matrix. STA analysis indicates better thermal stability of the NCs than that of pure PANI, and the terminal degradation temperature of NCs (670°C) is greater than the PANI/Fe₃O₄ NCs (570°C). Saturation magnetizations of NCs indicated an increase of ferromagnetic interaction with more incorporation of Fe₂TiO₅ in PANI matrix.
