“…During the last few decades, electrical and thermal properties of conducting polymer filled with metal nanoparticles received much attention due to its potential applications in molecular sensors, electromagnetic shielding materials, microelectronic, and nonlinear optical devices . Among the conducting polymers, polyaniline (PANI) gave much interest to the researchers because of its higher conductivity, cost‐effectiveness, easy synthesis, and environmental stability . However, PANI has poor solubility, thermal stability, and mechanical properties.…”

We report the preparation, characterization, and properties of polyaniline (PANI)/ phenothiazine (PTZ) blend with different concentration of titanium dioxide (TiO 2 ) nanoparticles. Formation of nanocomposites was monitored by Fourier transform infrared spectra, UV, X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HR-TEM), differential scanning calorimetry (DSC), and thermogravimetric analysis studies. Spectroscopic characterization confirmed the bonding structure of PANI/PTZ/TiO 2 composite through the shift in absorption peaks of nanocomposites compared to pure PANI/PTZ blend. XRD studies confirmed the presence of sharp crystalline peaks of TiO 2 in the blend system signifying good interaction among the adjoining molecular chain of polymer with the nanoparticles. Surface morphological details of the nanocomposites obtained using SEM and HR-TEM reveal the formation of hemispherical-like structures with a diameter of 15 to 30 nm. DSC measurements of these nanocomposites showed that the glass transition temperature was reduced as the concentration of TiO 2 increased into PANI/PTZ blend matrix. The influence of filler loading on thermal stability showed that the TiO 2 enhanced the thermal stability and reduced the rate of thermal degradation of polymer blend nanocomposites. Conductivity studies showed that both AC and DC conductivity, dielectric constant, and dielectric loss increase with an increase in the concentration of nano-filler TiO 2 up to 10 wt%. Similarly, the ammonia gas sensing behavior of nanocomposites was also improved by the addition of nanoparticles. From the characterization studies, it can be suggested that TiO 2 helps to achieve excellent thermophysical properties, gas sensing, electrical conductivity, and dielectric characteristics for PANI/ PTZ blend which can be used in the fabrication of electrical or nano-electronic devices.

“…The change in optical and structural characteristics happen as a result of doping the nanoparticles within the polymer main chains. The higher conductivity, cost-effectiveness, easy synthesis, and environmental stability of polyaniline (PANI) makes it more attractive than the other conducting polymers [15,16]. Yet, PANI is poor in terms of thermal stability, solubility, and mechanical characteristics.…”

The casting method was employed for the preparation of polymer blend films doped with TiO2 (0.5, 1, 1.5, and 2.3 wt.%). The XRD outcomes show that TiO2 phase formation is anatase, with an average crystal size of 20.25 nm. PANI/PMMA-TiO2 nanocomposites samples have an amorphous nature. In addition, the degree of amorphousity is increased with the increase of the content of the TiO2 NPs. The FTIR method was employed for presenting the vibrational bands of the nanocomposites and the intermolecular bonding of the blend with the TiO2 NPs. The applied investigation involved the optical constant like absorption as well as t90-etransmission spectra, refractive index, reflectance, coefficient extinction, dielectric constant’ imaginary and real parts, the susceptibility (χ3) of third order and the optical band gaps. The optical band gap (Eg) values of the films of fabricated nanocomposites was lower upon doping (≤ 1.5 wt.%). The reduction of the value happened due to the introduction of the preselected TiO2 NPs into thin films. Such values significantly match the values which were revealed by the Tauc technique. It was proved through DSC and TGA techniques that TiO2 NPs can lead to the enhancement of the polymer blend in terms of thermal stability. As displayed by the DSC analysis, there is a single Tg of the polymer blend (PANI/PMMA), which prove their miscibility. The optical constants displayed by the experimental results show noticeable changes upon raising the doping concentrations. The resultant doped thin films indicate that the fabricating high-efficient optoelectronic machines are greatly promising.
