Nanocomposite films made of polystyrene (PS) and polyvinyl carbazole (PVK) and filled with varying quantities of titanium oxide (TiO2) nanoparticles (NPs) were prepared using the solution casting process. The TiO2 NPs' impact on the pure PS/PVK blend's structural, optical, and conductive properties was investigated and explained. X-ray diffraction (XRD) and Transmission electron microscopy (TEM) measurements indicate that the synthesized TiO2 NPs' size ranges between 12 and 32 nm and has a tetragonal anatase phase. The XRD scans also indicate that the PS/PVK filling with TiO2 NPs decreases the nanocomposite crystallinity. Fourier transform infrared (FTIR) analysis shows the main distinctive absorption peaks of PS and PVK, whose intensities changed randomly after filling. Moreover, the highest TiO2 NPs content showed a new peak at 449 cm-1. The UV/visible measurements showed that the optical energy gaps for the direct and indirect permitted transitions decreased as the TiO2 NPs content increased. Using impedance spectroscopy at room temperature, the AC electrical conductivity of the PS/PVK mixture containing TiO2 NPs was investigated over a broad frequency range from 10-1 to 107 Hz. It has been shown that the frequency dependence of AC electrical conductivity obeys Jonscher's rule, and the increase of TiO2 NPs concentration in the blend induces the formation of a percolating network within the composite. It has also been shown that the composite's dielectric loss and constant increase with nanoparticle concentration.

Electromagnetic wave (EMW) radiation pollution is getting more severe as result of the advancement of electronic technology. Researching shielding materials with superior EMI (electromagnetic interference) shielding characteristics is therefore crucial. Basalt fibers (BFs) have been an emerging candidate in the fiber‐reinforced polymer (FRP) category due to their favorable mechanical and chemical properties, along with being favorites in sustainability and having low production costs. Therefore, due to the rising need for cheaper and efficient alternatives in the EMI shielding industry, the EMI shielding is covered in terms of BF composite materials and their properties in this review, starting with the EMI shielding mechanism and followed by how BF composites affect the EMI properties. This review then covers the post‐treatments of BF composites and, finally, the factors of the composites that affect the EMI properties. Moreover, the EMI shielding applications in which BFRPs are used are comprehensively discussed as well. This review aspires to bridge an understanding between EMI shielding as a material property and the BF composites that are developed to aid in the EMI shielding application.
