Abstract
Abstract The growth of the application of electronic devices has created a new form of pollution known as noise or radio frequency interference, electromagnetic radiation, or electromagnetic interference (EMI), which results in the malfunction of equipment. A new carbon-based polymer composite has been unlocked through the discovery of polymer composites. Carbon nanotubes (CNTs) have shown potential as reinforcement fillers in polymer to enhance an EMI shielding material owing to their large specific surface area, well-defined 3D networking structure, and unique electronic structure. The main focus of this review is the role of CNT as fillers in intrinsic conducting polymer and conducting polymer composite. The factors that influence EMI shielding performance are also included in this review. The roles of the size; shape; and electronic, mechanical, and chemical properties of nanomaterials in tuning the EMI shielding effectiveness of polymer hybrid are emphasized. The structural design of CNT polymer composite has been reviewed as well. Future research direction has been proposed to overcome the current technological limitations and realize the most advanced EMI shielding materials for future use. The composites have a potential to replace traditional shielding materials owing to their advantageous properties.

This review summarizes the current progress of polymerbased EMI shielding materials with emphasis on tunable material properties for effective shielding
Article 1.166 of the International Telecommunication Union’s Radio Regulations define EMI as the effect of unwanted energy because of one or a combination of emissions, radiations, or inductions upon reception in a radio communication system manifested by performance degradation or the misinterpretation or loss of information that could be extracted in the absence of unwanted energy with mathematical simplicity
Summary
Abstract: The growth of the application of electronic devices has created a new form of pollution known as noise or radio frequency interference, electromagnetic radiation, or electromagnetic interference (EMI), which results in the malfunction of equipment. Metallic and magnetic materials, such as copper, aluminum, steel, and iron, have been employed as effective shielding materials because of their high electrical conductivity and good permeability Despite their good EMI SE, EM pollution has not been completely eliminated or mitigated as EM signals are almost entirely reflected at the surface of the metal, which protects the environment only beyond the shield. Polymer hybrids must have high electrical conductivity/permeability to be utilized as an effective reflection/ absorption shield This property could be gained by incorporating electrically conducting/magnetic fillers into the polymer matrix. Carbon nanotubes (CNTs) have been used as conducting filler materials because these electrically conducting organic nanomaterials and their composite exhibit good EMI shielding performance. Future research directions are proposed to realize highly efficient polymer-based EMI shielding materials with optimized physical properties. Thicker samples generally give higher EMI SE; current demands are on thinner materials with high EMI SE [9]
