Construction of three-dimensional interconnected graphene nanosheet network in thermoplastic polyurethane with highly efficient electromagnetic interference shielding

Directional Electromagnetic Interference Shielding Based on Step-Wise Asymmetric Conductive Networks

“…Given the prosperity of electronic devices and modern telecommunication technology that are represented by newly emerged 5G wireless system, electromagnetic interference (EMI) pollution has become an inevitable and serious social issue that has greatly detrimental effects both on the operation of precision instruments and the health of human beings [1][2][3][4]. In order to attenuate undesirable electromagnetic (EM) wave, it is imperative and urgent to exploit high-performance EMI shielding materials [5][6][7][8].…”

Constructing hierarchical structure via in situ growth of CNT in SiO2-coated carbon foam for high-performance EMI shielding application

“…(3) The increase of CNT content and length can form an effective conductive network that accelerates the attenuation of the helimagnetic wave by ohmic losses in the pores. We also compare the shielding effectiveness of CMF@5SiO 2 -30CNT/PDMS with other reported composites by CMF-based materials in the X-band as listed in Figure 10 [23, [29][30][31][32][33][34]. It can be found out the difficulty to achieve a high EMI SE performance with a thin thickness.…”

A journey of thermoplastic elastomer nanocomposites for electromagnetic shielding applications: from bench to transitional research

“…Therefore, the present strategy paved a new way to fabricate EMI-shielding composites with comprehensive performances. In this research work Fu et al 152 fabricated an excellent and lightweight TPU-GNSs@MF composite. The resultant TPU-GNSs@MF composite with 3D porous structure had a high electrical conductivity of 45.2 S m À1 and an exceptional shielding effectiveness (EMI SE) of 35.6 dB in the X-band at only 2.01 vol% GNSs loading and 2 mm thickness of TPU-GNSs@MF composites.…”
