“…e DSC curve of PANI and PPy shows broad endothermic peaks at 359.95 K and 384.85 K, respectively. In literatures, PANI's T g was observed at 385.15 K [19], and PPy's T g was displayed at 371.15 K [20], indicating that our measured T g is close to the literature's reports within ∼10-20°C error. When evaluating the PPy : PANI 50 : 50 system in Figure 4(c), we observed that there is only single glass transition temperature.…”

We report on the miscibility and phase behaviour of polypyrrole-polyaniline (PPy/PANI) as a function of blend composition. The PPy/PANI blends were prepared by solution processing method, using dimethyl sulfoxide (DMSO) solvent. Characterization of the polymer blends was carried out based on the data analysis from Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and differential scanning calorimetry (DSC). The PPy/PANI system was successfully formed blends in DMSO solvent. The polymer blends showed almost amorphous nature in XRD spectra because of intermolecular interaction between PPy and PANI macromolecules, which was confirmed by FT-IR data. Specifically, the DSC result for the PPY : PANI = 50 : 50 wt.% blend showed only one glass transition temperature (Tg), which indicates that the two polymers are well miscible without undergoing any phase separation.

“…So, in situ polymerization method is executing in the synthesis of composites to ensure the homogenous dispersion of nanoparticles in the polymer matrix. 23 The electrical conductivity of insulating polymer can be enhanced by proper dispersion of conductive fillers. 24 There is an increased demand for flexible conductive composite by the incorporation of the relatively small amount (1-15 phr) of conductive fillers, which convert the thermoplastic material into a semiconductive one.…”

Electrically conductive nanocomposite system based on poly(butyl methacrylate) (PBMA) with different contents of neodymium-doped titanium dioxide (Nd-TiO2) was prepared by in situ free radical polymerization method. The effect of Nd-TiO2 on the morphology and structural properties of the composites was carried out by scanning electron microscope (SEM) and X-ray diffraction analysis (XRD). The temperature-dependent AC conductivity and DC electrical conductivity of PBMA/Nd-TiO2 nanocomposites were studied with respect to the different volume fraction of Nd-TiO2 nanoparticles. SEM and XRD patterns revealed the uniform dispersion and structural regularity of nanoparticles in the polymer matrix. The AC conductivity of PBMA and its composites were found to be increased with an increase in temperatures and frequencies. The activation energy and exponential factor were analyzed from AC conductivity and both results indicate the hopping conduction mechanism present in PBMA/Nd-TiO2 nanocomposite, which is responsible for the variation of conductivity with temperature also. The DC conductivity of nanocomposites was higher than pure PBMA and the conductivity increases with increase in the concentration of Nd-TiO2 nanoparticles. Experimental and theoretical investigations based on McCullough, Bueche, Scarisbrick, and Mamunya modeling were carried out to observe the DC conductivity differences induced by the addition of Nd-TiO2 nanoparticles in PBMA matrix. Among the various modeling studied here, Mamunya model shows better agreement with the experimental conductivity.

“…The deposition of metal oxide on the surface of the fabrics can endow them with antibacterial property, anti-static, gas sensitivity, ultraviolet resistance, electromagnetic shielding property, electrical conductivity and other properties [ 67 , 68 ]. For example, the semiconductor ceramic film materials such as SnO 2 , ZnO, Al 2 O 3 and other oxides [ 69 , 70 , 71 , 72 ]. They have gas-sensitivity, therefore they could selectively adsorb gases.…”
