For several decades, forming blend and composite of polyaniline (PANI) with insulating polymers has been a widely studied research area because of the potential applications of such blends, which have a unique combination of mechanical properties, the processability of conventional polymers and the electrical property of conducting polymers. The current review paper will emphasize PANI composites or blends with thermosetting polymer matrices. The enhanced electro-mechanical properties of the blends and composites depend on the uniform dispersion of the PANI particle in polymer matrix. Therefore, considerable studies have focused on improving the distribution of PANI particles within the thermoset matrices. In this review paper, all the parameters and conditions that influence the surface morphology and application of PANI thermoset blends and composites will be described systematically. Recent progress on PANI based thermoset system with multifunctional ternary composites research will be highlighted in this paper. Furthermore, encouraging applications of different PANI thermoset composites and blends are discussed, such as flame-retardant materials, lightning damage suppression, metal ion removal, anticorrosive coating, electromagnetic shielding, conductive adhesives, and sensing materials.

Summary The current research paper presents an investigation of the piezoelectric performances of five different polyvinylidene fluoride hexafluoropropylene (PHP) systems fabricated by electrospinning. Morphological and structural analyses of neat PHP, PHP/zinc oxide 1% (PHP‐Z), PHP/mesoporous silica 1% (PHP‐M), PHP/ZnO‐mesoporous silica at 1 wt.% (PHP‐MZ1), and PHP/ZnO‐mesoporous silica at 3 wt% (PHP‐MZ3) were carried out systematically by scanning electron microscopy, transmission electron microscope, energy‐dispersive X‐ray spectroscopy (EDX), and X‐ray diffraction (XRD). The microscopic analysis results show the formation of uniform ZnO nanoflakes of approximately 5 nm in diameter, whereas mesoporous silica particles form a uniform spherical structure with a typical diameter of 5 μm. Elemental analysis by EDX spectra confirms the presence of Zn, O, and Si in the prepared nanocomposites. The crystalline β‐phase of PHP in the Fourier transformation infrared spectra rises with the addition of ZnO and mesoporous silica particles to the polymer matrix. Neat polyvinylidene fluoride has the most intense XRD peak in comparison to all other polymer nanocomposites. The fabricated flexible nanogenerator obtained from the 1% ZnO‐mesoporous silica nanocomposite shows an output voltage of 2 V, whereas the nanogenerator prepared using the neat PHP sample exhibits an output voltage of ~120 mV. All of the results indicate that the 1% ZnO‐mesoporous silica PHP nanocomposite is suitable for constructing low‐powered wearable self‐driven electrical devices.
