Polyoxometalate-immobilized carbon nanotube constructs triggered by host–guest assembly result in excellent electromagnetic interference shielding

Abstract: In the era of fifth-generation networks and the Internet of Things new class of lightweight, ultrathin, and multifunctional electromagnetic interference (EMI) shielding materials have become inevitable prerequisites for the protection...

“…Since Keggin-type complexes exhibited better EMI SE with a lower concentration, therefore, during this course of study, we have deliberately chosen Keggin-type Cu-POM to investigate the effect of host–guest electrostatic assembly in EMI shielding performance. Since Keggin-type Cu-POMs are offering high negative charge density, as inferred from our earlier findings, 38 it can further augment and intensify the surface charges of the system with which they are integrated. 29 With this idea in mind, we planned to explore the conjugation of IPNs and Keggin-type Cu-POMs to host positively-charged functionalized CNTs to prepare a seamless construct and deploy them for effective EMI shielding applications.…”

“…37 Moreover, Keggin POMs exhibit highly stable redox states for participation in fast reversible multielectron transfer reactions. 36 In our previous work, 38 we have immobilized Keggin and Anderson type Cu-POMs in CNT constructs and investigated the EMI SE by varying the concentration of both Keggin and Anderson type Cu-POMs in the fabricated construct. Since Keggin-type complexes exhibited better EMI SE with a lower concentration, therefore, during this course of study, we have deliberately chosen Keggin-type Cu-POM to investigate the effect of host–guest electrostatic assembly in EMI shielding performance.…”

“…The synthesis of the Keggin-type copper substitute polyoxometalate (Cu-POM) employed a straightforward one-step hydrothermal process, adapted and refined from earlier literature, [28][29][30][31] with minor modifications. Initially, 1.5 g of CuSO 4 •5H 2 O was dissolved in 180 ml of deionized water within a glass container.…”

“…In our study, we synthesized copper-substituted polyoxometalate (Cu-POM) using a one-step hydrothermal process. 28–31 However, the suitable band gap, stability, and simple fabrication of POMs contribute to their appeal in addressing environmental challenges, supporting our incorporation of these unique nanoclusters for enhancing microplastic photodegradation in water. 32–34…”
