Governing the Ni content and size of 2D layered C/Ni nanoparticle composites for enhanced electromagnetic wave absorption

Ferromagnetic Elements in Two‐Dimensional Materials: 2D Magnets and Beyond

“…This is attributed to different resulting sizes and compositions of the 2D C/N NP composites. [154] Similarly, 2D organic 𝛼-Co(OH) 2 exhibited good absorption properties, and it can be used as a precursor for Co/C composites as well. Those materials possess the same absorption properties and additional corrosion resistance together with wetting effect characteristics, which are very important for environmental applications.…”

Facile synthesis of a rod-like Ni/TiO2/C nanocomposite for enhanced electromagnetic wave absorption

“…8 lists some microwave absorption performances for Ni, TiO 2 , and carbon material absorbers reported in the literature. [34][35][36][37][38][39][40][41][42][43] It can be seen that Ni/TiO 2 /C exhibited signicant advantages, such as sample loading and ideal RL min values. The advantages of Ni/TiO 2 /C could be mainly attributed to the ternary synergistic effect of Ni particles, TiO 2 , and carbon materials.…”

Magneto-Orientated Graphite Double-Layer Homo-Structure with Broadband Microwave Absorption

“…It can be seen that the power flow of the EM wave declines with increasing depth and maintains the same direction, and the gradual reduction of the power flow confirms the absorbing ability of the double-layer absorber. We compared our materials with recently reported advanced composite wave-absorbing materials (Table S1) [31][32][33][34][35][36][37][38][39][40][41][42] and doublelayer absorbers [Fig. 4(h)].…”
