“…In the dissipation mechanisms of EMI shielding, the attenuation by multiple reflections was mainly related to the successive reflection of different surfaces and interfaces, which was of great significance to the properties of EMI shielding materials. 209,210 The continuous reflection of EMWs on the interfaces would increase the propagation path to achieve the continuous attenuation of EMWs. [211][212][213] The typical shielding materials with multiple reflection and absorption mechanisms were conductive foams and porous CPCs with high specific surface areas.…”

The proliferation of electronic devices and wireless communication in our daily lives has led to a significant increase in electromagnetic pollution. This issue poses a serious threat to the proper functioning of electronic equipment as well as human health. Therefore, the investigation of materials with superior electromagnetic interference (EMI) shielding capabilities has garnered growing interest. In this paper, the mechanisms of EMI shielding were first introduced briefly. It was noted that the development of advanced EMI shielding materials involved adhering to principles such as minimizing reflection loss, enhancing absorption loss, and incorporating multiple internal reflections. The construction and shielding properties of traditional EMI shielding materials were introduced. Unlike metal materials with high densities and reflection loss, lightweight conductive polymer composites (CPCs) have been the most promising EMI shielding materials. Meanwhile, carbon‐based nanofillers such as carbon nanotubes and graphene nanosheets, along with two‐dimensional transition metal carbonitrides MXenes Ti3C2Tx, have emerged as the most promising and versatile conductive nanofillers for CPCs. The EMI shielding performance and loss mechanism of CPCs with homogeneous structure, segregated structure, laminated structure, and porous structure were introduced in detail. It was noted that the EMI shielding performance could be significantly improved by incorporating multiple structures into the same CPCs, such as a rational combination of segregated and porous structures. Finally, the challenges and development trends of CPCs for EMI shielding applications were discussed.Highlights Mechanisms of EMI shielding were introduced from aspect of energy dissipation. Structure–property of traditional EMI shielding materials was described. EMI shielding performance of CPCs with different structures was summarized. Future challenges and growing trends of CPCs for EMI shielding were discussed. Absorption‐dominated loss and multiple structure design were emphasized.

In the era of man–machine interfaces, digital twins stand as a key technology, offering virtual representations of real-world objects, processes, and systems through computational models. They enable novel ways of interacting with, comprehending, and manipulating real-world entities within a virtual realm. The real implementation of graphene-based sensors and electronic devices remains challenging due to the integration complexities of high-quality graphene materials with existing manufacturing processes. To address this, scalable techniques for the in-situ fabrication of graphene-like materials are essential. One promising method involves using a CO2 laser to convert polyimide into graphene. Optimizing this graphitization process is hindered by complex parameter interactions and nonlinear terms. This article explores how these digital replicas can enhance the fabrication of laser-induced graphene (LIG) through laser simulation and machine learning methods to enable rapid single-step LIG patterning. This approach aims to create a universal simulation for all CO2 lasers, calculating optical energy flux and utilizing machine learning to control and predict LIG conductivity (ability to conduct current), morphology, and electrical resistance. The proposed procedure, integrating digital twins in the LIG production process, will avoid or reduce the preliminary tests required to determine the proper laser parameters to reach the desired LIG characteristics. Accordingly, this approach will reduce the time and costs associated with these tests and thus increase the efficiency and optimize the procedure.
