“…The proliferation of smart electronic devices and wireless communication in the artificial intelligent age are a source of electromagnetic pollution (EMP) which is a serious universal problem. The EMP creates complexities in the natural electromagnetic environment, and is unwanted radiation which not only disturbs the general function of surrounding electronic systems but also threatens the well−being of humans [1][2][3][4][5][6][7][8]. This disturbing phenomenon is called electromagnetic interference (EMI) and it causes data theft, malfunction of the electronic devices, degradation of basic function of electronic devices, and vulnerability of the personal security in electronic components, while grounding problems in humans such as mutation, insomnia, headache, leukemia, damage the organs, thermal injuries, and cancer [1][2][3][4][5].…”

The two Dimensional (2D) materials such as MXene and graphene, are most promising materials, as they have attractive properties and attract numerous application areas like sensors, supper capacitors, displays, wearable devices, batteries, and Electromagnetic Interference (EMI) shielding. The proliferation of wireless communication and smart electronic systems urge the world to develop light weight, flexible, cost effective EMI shielding materials. The MXene and graphene mixed with polymers, nanoparticles, carbon nanomaterial, nanowires, and ions are used to create materials with different structural features under different fabrication techniques. The aerogel based hybrid composites of MXene and graphene are critically reviewed and correlate with structure, role of size, thickness, effect of processing technique, and interfacial interaction in shielding efficiency. Further, freeze drying, pyrolysis and hydrothermal treatment is a powerful tool to create excellent EMI shielding aerogels. We present here a review of MXene and graphene with various polymers and nanomaterials and their EMI shielding performances. This will help to develop a more suitable composite for modern electronic systems.

“…The x‐ray photoelectron spectra (XPS) of the composite films are shown in Figure S2. Besides, some previous studies indicated that well‐aligned CNTs built a superhydrophobic surface 52–55 . This is the reason that the addition of carbon nanotubes increases the surface roughness of the film and improves the hydrophobicity of the composite film, it can be seen from Figure S3, the surface roughness increases from 0.201 to 0.393Ra when the CNT content increases from 0 to 3 wt%,and it is also the result of the increasing water contact angle of the PP/PC/CNT composite film with the increase of CNT content.…”

In this study, CNT/PP/PC conductive composite films were prepared by compounding PP (polypropylene)/PC (polycarbonate) (1:1) and carbon nanotubes (CNT) using a physical blending and hot pressing method. Next, Fourier transform infrared spectroscopy, thermogravimetric analysis, differential scanning calorimetry, and water contact angle measurement are conducted in order to characterize the properties of CNT/PP/PC conductive films. The results showed there is no chemical reaction inside the PP/PC composite film with the addition of CNT. Neither the CNT composite film containing 3 wt% nor the control film decomposed thermally within 220°C. The water contact angle increased from 88.5° for the control film to 110.99° for the composite film containing 3 wt% CNT. This indicates that the film has good thermal stability and hydrophobic properties. The percolation threshold was obtained when the content of CNT was 3 wt%, and the best conductivity of the CNT/PP/PC composite film was 5.53 S/m at this time. In order to improve the tensile properties of the film, a small amount of polyurethane (TPU) was added to the film, and the maximum tensile strength was 24.91 Mpa when the content of TPU was 6.7%. This study can provide a strategy for the practical application of flexible electronic devices.

“…Mechanism of shielding of the EMWs has been a reflection and multiple reflections [128]. Since Ag is an excellent conductor, it is commonly used as a coating for many other particles to enhance their conducting properties [129,130]. Different fractions of Cu core shells coated with Ag (Cu@Ag) have been used in fabricating a lightweight and flexible EMI shielding composite with a leather matrix that can be worn.…”

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.
