“…So, it has been found that microwave absorbing materials have important role in EM interference shields and radar absorbers. Polymers [1,2], carbon materials [3,4], ferrites [5,6], nonferrite ceramics [7,8], magnetic metals [9,10] and hybrid materials [11,12] have been investigated for their microwave absorbing properties. Different morphologies, complex hierarchical and heterostructured nanoparticles are also considered for their enhanced EM properties.…”

“…ZnO being an important inorganic semiconductor have prompted much interest as transparent conductive oxides due to their valuable properties such as high optical transparency in the visible region, low electrical resistivity, as well as high electrochemical stability, abundance in nature, and absence of toxicity [19] . There are reports on EMI shielding of ZnO in the X band (8)(9)(10)(11)(12) and Ku-band (12)(13)(14)(15)(16)(17)(18) [20,21] . However, due to low conductivity, of late ZnO is doped with metal cation and its EMI shielding properties are studied.…”

The paper describes the mechanical properties and electromagnetic shielding (EMI) of Co doped ZnO-Poly(vinyl alcohol) (PVA) nanocomposite. Significant improvements in mechanical properties can be obtained by incorporating inorganic nano fillers. The EModulus and tensile strength were found to be enhanced with the increase in the doping concentration of Co .05 Zn .95 O incorporated in PVA matrix. Further, we have observed that EMI of the composite filled with 2 wt% concentration of Co .05 Zn .95 O in the PVA matrix exhibited utmost reflection loss of -47.31 dB in the bandwidth 8-12 GHz which may be attributed to good compatibility of dielectric and magnetic properties of materials.

“…The SE test has shown that this composite can have a SE above 38 dB. The Ag coating on the powder has increased the overall SE of the composite by increasing the multiple reflections, thus attenuating the EMWs [127]. One of the primary purposes of using a polymeric matrix to fabricate a composite for EMI shielding is to reduce the density of the composite.…”

Polymer matrix composites have generated a great deal of attention in recent decades in various fields due to numerous advantages polymer offer. The advancement of technology has led to stringent requirements in shielding materials as more and more electronic devices are known to cause electromagnetic interference (EMI) in other devices. The drive to fabricate alternative materials is generated by the shortcomings of the existing metallic panels. While polymers are more economical, easy to fabricate, and corrosion resistant, they are known to be inherent electrical insulators. Since high electrical conductivity is a sought after property of EMI shielding materials, polymers with fillers to increase their electrical conductivity are commonly investigated for EMI shielding. Recently, composites with nanofillers also have attracted attention due to the superior properties they provide compared to their micro counterparts. In this review polymer composites with various types of fillers have been analysed to assess the EMI shielding properties generated by each. Apart from the properties, the manufacturing processes and morphological properties of composites have been analysed in this review to find the best polymer matrix composites for EMI shielding.
