The current work delivers preparation of MXene-based magnetic nanohybrid coating for flexible electronic applications. Herein, we report carbon dot-triggered photopolymerized polynorepinepherene (PNE)-coated MXene and iron oxide hybrid deposited on the cellulose microporous membrane via a vacuum-assisted filtration strategy. The surface morphologies have been monitored by scanning electron microscopy analysis, and the coating thickness was evaluated by the gallium-ion-based focused ion beam method. Coated membranes have been tested against uniaxial tensile stretching and assessed by their fracture edges in order to assure flexibility and mechanical strength. Strain sensors and electromagnetic interference (EMI) shielding have both been tested on the material because of its electrical conductivity. The bending strain sensitivity has been stringent because of their fast ‘rupture and reform’ percolation network formation on the coated surface. Increased mechanical strength, solvent tolerance, cyclic deformation tolerance, and EMI shielding performance were achieved by decreasing interstitial membrane porosity. Considering a possible application, the membrane also has been tested against simulated static and dynamic water flow conditions that could infer its excellent robustness which also has been confirmed by elemental analysis via ICP–MS. Thus, as of nurturing the works of the literature, it could be believed that the developed material will be an ideal alternative of flexible lightweight cellulose for versatile electronic applications.

“…High specific gravity, corrosion, lack of flexibility, and poor processibility are all important drawbacks of traditional metal-based EMI-shielding materials. Carbon nanomaterials such as carbon nanotubes (CNTs), graphene, reduced graphene oxide (RGO), and other conducting polymers have been widely used to alleviate these limitations. − Besides this, lightweight EMI-shielding materials with all desirable properties have garnered great attention from the scientific community due to their practical applications in aerospace, radar, portable devices, heavy machinery, and so forth. − …”

Solid matrix-supported liquid metal nanoparticles have been drawing attention as a nanoadditive in the fabrication of electroconductive flexible and soft materials. The present work reports a facile, green, and sonochemical synthesis approach of gallium (Ga) nanoparticles embedded in reduced graphene oxide (RGO) under ambient conditions for the first time. The as-synthesized ultrasonic energy-irradiated RGO/Ga nanocomposite was studied using SEM, TEM, DSC, XRD, XPS, and solid-state NMR. Because of their electrical conductivity, RGO/Ga nanoparticles have been used as a conducting inclusion for a poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) matrix and coated on cotton fabrics to develop a smart e-textile for electromagnetic (EM) radiation-shielding application. In the X-band (8.2–12.4 GHz) frequency range, the nanocomposites’ EM interference-shielding efficiency was about 34 dB. Moreover, because of the liquid metal–graphene interfaces; the fabricated materials were excellent heat conductors reporting ∼44% increment in thermal conductivity compared to a bare fabric. The coated cotton textile’s durability was tested under various conditions. The hard phase of the RGO/Ga nanoparticles is disseminated throughout the fabric, while the polymeric soft phase, that is, PEDOT:PSS macrochains, tended to interlink among the dispersed phases to construct a large spatial conducting network. Therefore, such a lightweight, flexible, and conductive e-fabric could be used not only for mitigating EM pollution but also as an alternative to commercial metallic EM wave absorbers in telecommunication, aerospace, and next-generation flexible electronics areas.

“…Although metals provide good EMI shielding effectiveness, they confront drawbacks such as low corrosion resistance, high cost, problematic processing and forming, and high weight . Conductive polymer composites (CPNs) made by incorporating conductive fillers in insulating polymer matrices revealed appropriate electrical properties and EMI shielding effectiveness for electronic devices to fulfill electromagnetic compatibility requirements . The electrical conductivity, dielectric, and EMI shielding properties of CPNs depend on not only the weight percent, aspect ratio, and intrinsic conductivity of the fillers but also the dispersion and distribution of the fillers in the polymer matrices .…”

In this study, electrical properties and electromagnetic interference shielding effectiveness (EMI SE) of composites based on room temperature vulcanizing silicone rubber (RTV-SR) and hybrid conductive fillers (carbon black [CB]) and graphite nanoplate [GNP]) were studied. The role of GNP/CB ratio on developed conductive networks, electrical properties, as well as electromagnetic interference (EMI) shielding effectiveness of composites was investigated in comparison with SR/CB and SR/GNP composites. Dielectric properties of hybrid composites were controlled by the dominant filler phase. Nevertheless, all hybrid nanocomposites with a higher fraction of CB in GNP/CB hybrid systems showed a lower percolation threshold and higher EMI SE. The frequency dependency of the AC conductivity revealed tunneling conduction mechanism below the percolation threshold, while above the percolation threshold, the direct contact mechanism played the dominant role of transferring electrical current. EMI shielding measurements over X-band frequency demonstrated absorption loss as the main mechanism for the attenuation of the incident EM wave intensity in hybrid composites. POLYM.
