Salt-templated graphene nanosheet foams filled in silicon rubber toward prominent EMI shielding effectiveness and high thermal conductivity

Graphene in rubber formulations: a comprehensive review and performance optimization insights

“…A higher ratio of I D / I G reveals a higher defect density in graphene. 71,72 The I D / I G ratio of gelatin-modified rGO increases from 0.85 to 1.03 indicating the efficient exfoliation of rGO by gelatin causing a more disordered structure. As a result, 1 phr of gelatin-modified rGO contributes to 36.7% and 35% reduction in internal heating and maximum temperature, respectively, in a natural rubber tire.…”

Synchronous achievement of ultra-wideband microwave absorption and high thermal conduction in spongy TiO2-based magnetic composites via constructing magnetic/dielectric double loss and phonon/electron co-transmission

“…The integration and miniaturization trend of high-frequency and large-power electronic devices, brought into being by the 5G/6G communication era, has exacerbated electromagnetic interference (EMI) and overheating issues. [1][2][3] The EMI may affect the performance of electronics, leading to information disclosure and even data loss; [4][5][6] besides, excessive heat that cannot be dissipated may cause the core chips to age rapidly or even malfunction. 7,8 To address these issues, multifunctional materials with excellent EM wave absorption and high thermal conduction have attracted considerable critical attention.…”

“…2 To achieve high TC and excellent EMWAP at low loading, the construction of a spongy or foam structure with a 3D interconnected framework might be a practical strategy. 3,8,10 In this study, spongy TiO 2 @Ni@C and TiO 2 @CoTiO 3 @-Co@C composites with magnetic-dielectric double loss and electron-phonon double heat-carriers were synthesized via a hydrothermal-soaking-annealing route. For tuning the thermal/magnetic/electrical/EM wave absorption properties of the as-obtained products, the molar ratios of Ni 2+ /Ti 4+ or Co 2+ /Ti 4+ (j) were controlled to adjust their Ni 0 /Co 0 content, defects, and texture.…”

In situ generated gas bubble-directed self-assembly of multifunctional MgO-based hybrid foams for highly efficient thermal conduction, microwave absorption, and self-cleaning

“…In contrast, hybrid foams can maximize the thermal flux of materials by coupling 3D interlinked networks with thermal conduction, which greatly improves the heat dissipation of integrated circuits and heat exchangers. 22 Besides, the hybrid foams are also qualified as an EMW absorbing/shielding material to eliminate EMI in electron devices due to their large interface polarization, abundant air-filled pores, and low dielectric constants. To date, various synthetic strategies have been developed to prepare metallic/nonmetallic hybrid foams, including templating, 23 sol-gel assembly, 24 nanosmelting, 25,26 and combustion synthesis.…”
