“…The observed spectrum clearly indicates the occurrence of broad peak between 2θ = 22° and 28°, which is due to (110) plane, and it is the charac teristic peak of PANI [50]. Thus, it may be concluded that the structure of pure PANI is amorphous as reported in the literature [51]. The pattern of amor phous broad peak (22°-28°) in PANI is present in all PANI-Fe 2 O 3 composites according to its proportion.…”

Nanocomposites of polyaniline with Fe 2 O 3 particles have been synthesized by chemical oxidative polymerization method by increasing the weight percentage of Fe 2 O 3 . The powder X ray diffraction tech nique was employed to study the structure and crystallinity of the synthesized nanocomposites. The strong interaction of polyaniline with Fe 2 O 3 particles was confirmed using FTIR technique. It was shown that poly aniline is dispersed into Fe 2 O 3 particles successfully by in situ polymerization and therefore the degree of crystallinity increased due to crystalline structure of Fe 2 O 3 particles. According to SEM and TEM data, most of Fe 2 O 3 particles were coated with polyaniline and those nanocomposites have formed a network during the polymerization process as well. Electrical conductivity of polyaniline containing 5 wt % of Fe 2 O 3 was higher among all other composites and even than PANI.

“…Since then, tremendous work has been done using the concept of organic-inorganic nanocomposite, based on clay and other polymer matrices, such as epoxy resins [7][8][9], polyamides [10][11][12], polyimides [13,14], polyurethane [15], and polypropylene [16]. In the recent years, the breakthrough advancement of nanotechnology has inspired people to combine clay with another special class of matrix materials known as the intrinsically conducting polymers (ICPs) to form ICP-clay nanocomposites [17].…”

Given the availability of a wide range of properties not possessed by individual materials, nanocomposites based on conducting polymers and inorganic materials have attracted much deserved attention. However, there has been little attempt to optimize the synthesis and thermal properties of polyaniline–clay nanocomposites. In this study, the synthesis and thermal properties of polyaniline (PANi) and polyaniline–clay nanocomposites (PACN) were performed by systematically varying the feed composition. Both PANi and polyaniline–montmorillonite (MMT) nanocomposites were prepared by using ammonium persulfate (APS) as the oxidant. The chemical structure of the nanocomposites was studied by Fourier transform infrared spectroscopy (FTIR). FTIR spectra confirmed the presence of clay in the nanocomposites and the existence of mainly the emiraldine form of PANi. Thermal analysis was performed by using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The morphology and structure of PANi and PACN were studied by scanning electron microscopy (SEM), wide-angle X-ray diffraction (WAXD), and transmission electron microscopy (TEM). Our results confirm the intercalation and partial exfoliation of clay. This study also showed that increasing the oxidant concentration resulted in decreasing thermal stability and melting temperature of PANi. The reinforcement of PANi with MMT resulted in increased thermal stability and increased melting point of PANi. It was also shown that the addition of only about 0.1 wt% of APS resulted in an optimal thermal stability and melting point for PANi.
