“…PDMS composites enhanced the mechanical property, hydrophobicity and flexibility of the composite and EMI shielding did not change after performing 100 cycles of bending Figure 5g. [82] Li et al [144] prepared stretchable and conductive composite films of PEDOT: PSS and waterborne polyurethane (WPU) and investigated their EMI shielding properties in X-band region. At a loading of 20 wt% PEDOT: PSS, the composite films exhibited a conductivity of 77 S cm −1 and the highest conductivity recorded was 185 S cm −1 at 40% loading of PEDOT: PSS.…”

“…PEDOT: PSS was coated over polymer matrixes having hydroxyl groups such as cotton fiber, cellulose fiber, cotton pad, glycerol derived polyacrylonitrile (PAN) fiber, polyvinyl alcohol (PVA), and polyethyelene oxide (PEO) to improve the mechanical properties of PE-DOT: PSS. [80][81][82][83] Dispersion of carbonic fillers such as MWCNT, graphene and carbon nanofibers into PEDOT: PSS forms extended conductive path to tailor the EMI shielding properties. Metal nanoparticles and nanowires, such as iron, Cu, Ag NP, Ag NW added with PEDOT: PSS form additional electrically conductive network and improve electrical conductivity of composite materials which can directly influence the EMI shielding properties.…”

Recent technological developments have made the emission of electromagnetic (EM) radiation a significant source of electromagnetic interference (EMI). These EMIs consist of stray EM radiations that damage and malfunction electronics and telecommunication systems. Scientists have made countless efforts to solve these problems. The demand for EMI shielding materials is fast growing due to the increasing complexity of the EM environment and EMI. Poly(3,4‐ethylenedioxythiophene): polystyrene sulfonate (PEDOT: PSS) is an intrinsically conductive polymer that has attracted attention due to its high electrical conductivity, processability, and environmental stability. The use of PEDOT:PSS as a shielding material for EMI is a promising alternative to traditional metal‐based materials. This review provides an overview of different strategies explored for the preparation of PEDOT: PSS‐based composites for EMI shielding and the use of carbonic fillers, metal and metal nanoparticles, magnetic particles, and MXenes in these composites. The advantages and disadvantages of different approaches are discussed, and future perspectives for the development of PEDOT:PSS composites for EMI shielding are presented. The paper concludes that PEDOT‐PSS‐based composites offer significant potential for the development of lightweight, thin, flexible, and cost‐effective green EMI shielding materials, and continued research in this field can lead to their widespread commercialization and adoption.

“…[11,12] By incorporating conductive nanofillers into a polymer matrix, nanocomposites offer enhanced electrical conductivity, improved absorption capabilities, and excellent mechanical flexibility. Various nanofillers, such as carbon nanotubes, [13] graphene, [14] and conductive polymers, [15] have been explored to achieve high EMI shielding performance. Among them, MXene, a class of 2D transition metal carbides or nitrides, have gained significant attention due to their high electrical conductivity, thermal conductivity, and mechanical flexibility.…”

Extensive utilization of electronic devices and wireless equipment require human to take affirmative measures to weaken unwanted electromagnetic wave radiations. Herein, a ferroelectric poly[(vinylidenefluoride‐co‐trifluoroethylene) (P(VDF‐TrFE)‐MXene]‐poly(3,4‐ethylenedioxythiophene) (PEDOT) multilayered film is developed that can increase electromagnetic interference (EMI) shielding performance through electrical polarization. The MXene is encapsulated by a P(VDF‐TrFE) matrix, which inhibits oxidation, and a highly conductive MXene is created conductive network resulting in enhancement EMI shielding effectiveness (EMI SE). Furthermore, the surface pattern inducing multiple scattering and PEDOT layer contributes to the increasing absorption due to the electrically conductive PEDOT. Thanks to the electrically polarized and negatively charged P(VDF‐TrFE)‐MXene, the composite film demonstrates superior EMI SE and absolute EMI SE (SSEt) are exhibited remarkable ≈61 dB and 15230 dB cm2g−1 with high absorptivity (0.87) at thickness of 120 µm in X‐band. Additionally, P(VDF‐TrFE)‐MXene composite film is applicable to motion and thermo‐resistive sensor due to the negatively charged P(VDF‐TrFE) and thermo‐resistive property of PEDOT, respectively, for multifunctionality. This work provides a feasible avenue for flexible absorption dominant EMI shielding materials via electrical polarization with remarkable EMI shielding performance.

The design and preparation of lightweight and flexible electromagnetic interference (EMI) shielding composites with high efficiency and low reflection are critical to the electronic field. First, silver nanowires (AgNWs) were vacuum filtered on the electrospun thermoplastic polyurethane (TPU) fibrous film. Then, by combining the adhesive with the electrospun silicon carbide nanowhisker (SiCnw) @TPU composite fibrous film, the asymmetric EMI shielding composite films with high electromagnetic shielding efficiency (EMI SE) and low incident power were obtained. The lower AgNWs‐TPU layer provides the primary EMI SE, and the upper SiCnw@TPU fibrous film is used for electromagnetic wave absorption. This unique asymmetric structure, the synergistic effect of SiCnw's particular absorbing function and the excellent conductivity of the AgNWs layer make the film show high overall SE (SET = 55.18 dB). In order to improve the absorption effect of the composite film, the number of layers of SiCnw@TPU was adjusted, resulting in a final reflection coefficient value as low as 0.55. This work proposes a new strategy for developing EMI shielding composite films with high efficiency and low reflection, serving as a reference.
