The electromagnetic inference is an issue from decades, where working for a better shielding material is still on-going. The purpose of this study is to review the existing methods in the formation of graphene, metal and polymer-based composites. Study indicates that in graphene and metal-based composites, the utilization of alternating deposition method showed the highest shielding effectiveness, whereas, in polymer-based composite, the utilization of chemical vapor deposition method showed highest shielding effectiveness. However, this review reveals that still there is a gap in the literature in terms of the selection of the method. Although there are various available methods which researchers adopt as per their convenience, none of the studies makes a comparison of the methods to form a similar composite. Therefore, as a future gap researcher needs to adopt various methods to form a single composite and then make a comparison of shielding effectiveness. This act will be useful for future researchers to select the appropriate method.

Abstract Conducting polymer films produced by electropolymerization technique are highly conductive, simple, and suitable for use especially in electronic devices. An attempt has been made to produce polypyrrole-poly(vinyl alcohol) (PPy-PVA) conducting polymer composite films using 0.1 m p-toluene sulfonate dopant at a potential of 1.2 V (vs. standard calomel electrode) on indium tin oxide glass electrode. The potential application of the prepared PPy-PVA conducting polymer composite films as an electromagnetic interference (EMI) shielding material has been investigated in the present study. The EMI shielding effectiveness of PPy-PVA composite films prepared from different experimental conditions was analyzed in the microwave frequency range of 8–12 GHz. The shielding effectiveness of 45.67–35.7 dB has been demonstrated by PPy-PVA conducting polymer composite films, which appears to be very attractive in any EMI shielding applications where a minimum shielding effectiveness of 35 dB is required.

EMI shielding technique by using appropriate shielding material in an enclosure is commonly effective to block signal penetration. This paper presents the investigations on EMI shielding effectiveness of multilayer carbon fiber composites for architectural shielding purposes. The properties of carbon fiber such as high thermal conductivity, corrosion resistant, high tensile strength and excellent EMI shielding property make it suitable to be applied in building construction. The concrete samples with insertion of carbon fiber sheets were undergone the EMI penetration test which is based on IEEE standard testing procedures. These customized structures are proven to reduce signal penetration significantly in the high frequency range up to 2 GHz.
