“…The tensile strength and elongation at break decreased, while the Young's modulus increased as the NR‐PAni fraction in the blends increased. A more severe decline in the mechanical properties has been reported when PAni was blended, even at lower loading, with other thermoplastics, such as polyethylene terephthalate .…”

“…The tensile strength of the PVC/Al composites decreases with increasing the Al content due to the nonuniform filler loading between filler and matrices. Nand et al reported that the tensile strength, Young's modulus, and elongation‐at‐break values of linear low‐density polyethylene exhibited a higher tensile strength and elongation at break than the linear low‐density polyethylene (LLDPE)/natural rubber (NR)‐PAni blend samples. The tensile strength and elongation at break decreased, while the Young's modulus increased as the NR‐PAni fraction in the blends increased.…”

The effect of polyaniline (PAni) on the tensile properties, electrical conductivity, morphology, and thermal degradation of (poly[vinyl chloride])/(poly[ethylene oxide])/PAni (PVC/PEO/PAni) conductive films was studied. The tensile strength and modulus of elasticity of PVC/PEO/PAni conductive films decreased with an increase in the PAni loading. At high PAni content, the PVC/PEO/PAni conductive films exhibited higher electrical conductivity and thermal stability than lower filler loadings. A scanning electron micrograph morphology study showed that the PAni could significantly improve interaction at the interface of the filler into the PVC/ PEO phase. The PVC/PEO/PAni conductive films are known to interact with chemical samples while maintaining good compatibility and good application of conductive polymer for use in gas sensors. J. VINYL ADDIT.

“…According to Nand et al 27 , this behavior is attributed to the dissimilarity in the polarity of the polymers: while HDPE and LLDPE are typical non-polar hydrocarbon polymers, PANI possesses high polarity due to the presence of amine groups in its macromolecular structure. The fracture surface morphologies of the HDPE/LLDPE/ HDPE-g-MA/PANI composites with different contents of PANI are shown in Figure 5.…”

In this work, polyaniline (PANI) in emeraldine-base form, synthesized by chemical oxidation polymerization, was protonated with hydrochloric acid (HCl). Composites based on high-density polyethylene (HDPE) and linear-low density polyethylene (LLDPE) blends with PANI were prepared in molten condition using a torque rheometer. The effect of compatibilizer agent (maleic anhydridegrafted high density polyethylene, HDPE-g-MA) and different contents of PANI on the blends-based composites was also investigated. Thermal, mechanical, and electromagnetic (electric permittivity) measurements and morphological aspects of the composites were evaluated. The addition of PANI content in the composites decreases the degree of crystallinity of HDPE and LLDPE blends, which implies that PANI particles make it difficult for co-crystallization to occur in the HDPE and LLDPE, respectively. On the other hand, the addition of compatibilizer agent in the HDPE and LLDPE blends increased the degree of crystallinity. The complex parameters of permittivity in the frequency range of 8.2 to 12.4 GHz varied as a function of the PANI content in the blend. It was also observed that the compatibilizer agent increased the composite stiffness and decreased the electric permittivity values. This result shows that the increasing rigidity of the molecular structure of the polyethylene matrix hindered the dissipation of the electromagnetic energy in the sample.

“…Similarly the crystallinity of resulting composite was calculated using formula X c = (ΔH f / w ΔH f *) x 100, where 'w' stands for weight percentage of functionalized LDPE in the composite [15]. As per Table II, the resultant composite exhibit a little higher onset temperature, peak melting temperature and crystallinity pointing toward ease of manufacturing as per polymer industry.…”

Nano composite based on polyaniline (PANI) nano fibers filler and chromic acid functionalized low density polyethylene (LDPE) matrix with biocompatibility and low percolation threshold value was prepared via twin screw extrusion process. Density measurement, Fourier Transform Infrared Spectroscopy (FTIR), Field Emission Electron Microscopy (FESEM), Energy-dispersive X-ray spectroscopy (EDX), X-ray crystallography (XRD), Brunauer, Emmett and Teller analysis (BET), Thermo Gravimetric (TGA), Differential Scanning Calorimetery (DSC) and Four-Probe Conductivity measurements are reported. As low density polyethylene functionalization renders LDPE more biocompatible, it also facilitates conductivity due to carbon carbon double bonds, sulfonic, and carbonyl group moieties. PANI nano fibers also assist in charge transfer mechanism of resultant composite. Overall results indicate the formation of highly stable nanocomposite materials, with good physiochemical properties and conductivity. The resultant blend may prove beneficial as a low cost biocompatible and electrically simulated nerve tissue repair scaffolds.
