Conducting polymer based composites as efficient EMI shielding materials: A comprehensive review and future prospects

Electromagnetic interference (EMI) has been identified as one of the ever increasing unfortunate byproducts due to the exhaustive implementation of numerous electronic devices and systems. In order to control EMI and associated problems, there is increasing need for efficient shielding materials. It is well-known that single composition materials cannot provide the required EMI shielding efficiency, various composite materials with different combination of dissimilar materials have been fabricated. Among the various class of composite materials developed as EMI shielding materials, conducting polymer based composites have gained special recognition owing to their unique properties such as light-weight, processability, environmental stability, long life, durable, and less corrosive with tunability. This review paper gives a comprehensive survey on the recent works on conducting polymer based composites towards EMI shielding applications. • Systematic review on recent development in EMI shielding materials using conducting polymer based composites. • Incorporation of suitable organic, inorganic, and other nano-fillers results in the synergistic responses. • Conducting polymer based composites have great potential in the fabrication of broadband EMI shields. • Most suitable EMI shielding polymer composites exhibited attenuation capabilities of more than 99.999%. • Main directions for future research and applications are identified.
