“…Firstly, 0.2M ammonium persulphate (APS) was added drop wise drop to the mixture of 0.2M aniline and hydrochloric acid. During dropping of APS with continuous stirring in ice bath, the mixture mutation from colorless to dark green color 18) . At this stage, the (20 wt.％) 0.02 g Sm 2 O 3 -TiO 2 binary oxide was added to the reaction mixture and kept at same conditions 24 h. After that, the formed was filtered and washed several times by ammonium solution to remove acid ions and natural the pH and deionized water.…”

In the last years, a major attention has been concentrated on the fabricate of conducting polymers doping by nanoparticles because of its unrivaled chemical and physical properties 1−3) . in from between the polymers, polyaniline (PANI) has a large attention to researchers and most widely investigated since it shows excellent stability, ease of prepare, tunable properties, low cost and wide use in electric application such as gas sensor, supercapacitor and batteries 4−7) . Polyaniline with among metal oxide nanoparticles have been studied widely due to their unique size dependent chemical and physical properties creation via the inserting of oxide nanoparticles in the matrix of polymer 8,9) . Clearly this enhances the electrical conductivity, thermal stability, mechanical properties and conductivity process ability for the matrix of polymer. Usually, there are two methods utilize for synthesis PANI-metal oxide nanocomposite. The most commonplace and generally tried method

“…PANi is one of the most popular conductive polymers due to its high electrical and thermal properties among polymers, and it also has reversible acid-base characteristics. The PANi is a singular and hopeful conducting polymer due to its simple fabrication, low price, elevated environmental stability, and steady electrical conductivity [9]. However, the PANI has limited utilization because of its fusibility, mechanical properties, weak solubility, and processability [10].…”

Flexible nanocomposite thick films consisting of PVA0.7PANi0.3 polymer blend doped with different concentrations of functionalized Graphene (FGNPx) (where x = 0, 5, 10, 15, 20, and 25 wt.%) were synthesized using the solution cast technique. Scanning Electron Microscopy (SEM), X-ray diffractometer (XRD), Energy Dispersive Spectroscopy Analysis (EDX), and Fourier- Transform Infrared Spectra (FT-IR) were used to study the structure of the samples. The results showed that the ordered structure, its orientation, the PANIs' well dispersion, the 𝜋 − 𝜋 stacking, and the electrostatic forces play a significant role in enhancing the interfaces between the polymer blend and the FGNP. Thermogravimetric Analyses (TGA) and Thermoelectrical analyses (TE) showed that the PVA-PANI conducts a promised conjugated blend for thermoelectric applications. The introduction of the FGNP contents into the blend increased the TE measurements as the DC electrical conductivity ≈ 0.0114 (S.cm−1), power factor ≈ 3.93x10− 3 (W.m−1 .K−2 ), and Z.T. ≈ 8.4x10− 7, for the 25 wt. % FGNP nanocomposite film. The effect of the polymers’ phonon contribution in the thermal conductivity controlling and enhancing the thermal stability of the prepared nanocomposite films.
