“…The IR spectra of the Cl‐NR/PIN blend show all the characteristic transmittance associated with the counterparts present in the blend system. The broad band appeared at 3447 cm −1 , representing the NH stretching vibration of PIN in the blend 30 . This broad appearance of the NH peak indicates that the nitrogen atom is not involved in bond formation in the blend system.…”

“…This broad appearance of the NH peak indicates that the nitrogen atom is not involved in bond formation in the blend system. The peak at 1459, 1385 cm −1 indicates the CN and CN stretching 30 . The bands at 1655 and 722 cm −1 are ascribed to the stretching of benzene ring in polyindole component of the blend.…”

The synthesis of highly flexible conductive rubber blend nanocomposites using a conductive polymer with metal oxide is a new and promising approach. In this work, the effect of titanium dioxide (TiO 2 ) on the performance of chlorinated natural rubber/polyindole (Cl-NR/PIN) blend nanocomposites was systematically studied. Fourier-transform infrared spectra revealed the successful incorporation of nanoparticles in the blend system. UV analysis assessed the increased absorption spectra of the nanocomposite compared to the pure blend. The X-ray diffraction confirms the presence of TiO 2 nanostructure in the blend. The high resolution transmission electron microscope results exhibited the uniform dispersion of TiO 2 in the blend. Differential scanning calorimetry and thermogravimetric analysis show the increased glass transition temperature and thermal stability of the blend nanocomposite with an increase in TiO 2 concentration. The linear low-frequency AC conductivity demonstrated the occurrence of electrode polarization and the exponential increase in AC conductivity after a threshold frequency illustrated the semiconducting behavior of the composites. The maximum dielectric constant and AC conductivity were measured for the composite with 5 wt% filler loading, as the threshold level for the maximum interfacial contact. The hopping conduction, activation energy, improved conductivity and dielectric properties suggest that these blend nanocomposite films are promising candidates for the development of flexible energy storage devices.chlorinated natural rubber/polyindole blend, dielectric parameters, nanocomposites, temperature dependent conductivity, thermal properties, titanium dioxide | INTRODUCTIONConducting polymers are of great interest due to their diverse applications such as rechargeable batteries, modified electrodes, biosensors, electrochromic displays, and primer layers that prevent corrosion. [1][2][3] The nitrogencontaining heteroaromatic polymer has several intriguing properties, but the main barrier is its poor mechanical stability, brittleness and low processability. Polyindole (PIN) films are often particularly rigid, brittle, insoluble,
