Synthesis of PANI/Iron (II, III) Oxide Hybrid Nanocomposites Using SolGel Method

Abstract

A polyaniline/iron (II,III) (PANI/Fe₃O₄) hybrid nanocomposites were synthesized using a sol-gel method. The characterization of PANI/Fe₃O₄ hybrid nanocomposites were studied by Fourier transforms infrared spectroscopy with attenuated total reflectance (FTIR-ATR), multimeter, and permanent magnet. The FTIR result indicated that the PANI/Fe₃O₄ hybrid nanocomposites were successfully synthesized due to the chemical interaction was occurred by comparing a spectra of Fe₃O₄, polyaniline (PANI) and PANI/Fe₃O₄ hybrid nanocomposites. The electrical conductivity and magnetic properties of PANI/Fe₃O₄ hybrid nanocomposites were clearly performed using a multimeter and a permanent magnet, respectively. Application of external field to the sample have resulted 0.1 mV and 0.001 V DC readings for conductivity. While a Fe₃O₄ in the hybrid nanocomposites shows attractions to the permanent magnet, thus producing a magnetic field.

Structural and optical properties of α-Fe2O3 nanoparticles realized by simple thermal decomposition route

“…Peak positions for Fe4, Fe44 and Fe45 spectrum is 471, 550; 481, 526; and 493, 522 cm −1 , respectively. Observation of 471, 550 cm −1 peaks in Fe4 sample is signature of Fe-O vibrational mode present in Fe 3 O 4 polymorphs [23]. Further, it can be seen that there is blue shift (471→493 cm −1 ) in the low wavenumber peak with increasing repeated calcination temperature (Fe4→Fe45), while red shift (550→510 cm −1 ) in higher wavenumber peak.…”

Ternary Hybrid Materials for Highly Sensitive Acetone Sensing at Room Temperature

“…Since Fe 3 O 4 is a hydrophobic material, chemical reactions with PANI increase its dispersions in solution. It also shows good electrical behavior when an external electric field is applied to the material [29].…”

“…On the other hand, the combination of polymers with iron oxide nanoparticles has attracted much attention in conductive polymer applications due to their structures as well as their chemical and physical properties. It has been proven that the hybridization of iron oxide on the network of the polymer material results in better conductivity and magnetization by generating an electromagnetic field (EM) [17,29,30]. Many researches have been carried out and have shown the advantages of inorganic compounds in the PANI matrix, especially magnetite (Fe 3 O 4 ).…”

Synthesis and Characterization of Conducting Polyaniline Based on ANI-PVA-MgCl2Composites Using Gamma Radiation Technique

“…Recent studies have produced conducting PANI composites by employing several techniques, including sol-gel method [21], chemical methods [22], electropolymerization method [23], in-situ chemical oxidation polymerization [24], insitu polymerization technique [25], solution casting [26], via a sonochemical method [27], and aqueous solutions [28]. The irradiation of polymers is achieved using either gamma-rays, electron beams, or ionizing radiation [29].…”
