The extensive growth of telecommunication and electronic devices has led to significant concerns regarding electromagnetic (EM) radiations. Thus, the effect of EM radiations can be reduced by using highly efficient shielding materials. This review aimed to explore the electromagnetic interference (EMI) shielding materials based on polyvinylidene fluoride (PVDF), polyurethane (PU), and polyaniline (PANI) composites. It was found that the composites based on PVDF, PU, and PANI polymers have attracted considerable interest and highly efficient for EMI shielding due to their remarkable properties like lightweight, thermal stability, processing benefits, cheap, tremendous flexibility, and excellent resistance to corrosion. Hence, the PVDF-, PU-, and PANI-based composites are efficient EMI shielding materials.
