Embedding magnetic 3D carbon skeleton in SiCN ceramics for high-performance electromagnetic shielding

Research Progress on Intrinsically Conductive Polymers and Conductive Polymer-Based Composites for Electromagnetic Shielding

“…In addition, the Ni distributed on the CS not only catalyzes the formation of carbon nanowires (CNWs) in the matrix, but also reacts with Si to form NiSi to affect the magnetic properties of the ceramics, resulting in a significant improvement in the EMI SE of the material. The EMI SE of the composite ceramic X-band is greater than 55 dB when the plating time is fixed at 50 min for the preparation of ceramic composites [32].…”

Advancements in 3D-printed architectures for electromagnetic interference shields

“…Compared to metal-based electromagnetic shields and conductive polymerbased electromagnetic shields ceramic-based electromagnetic shields not only have an absorption effect but can also effectively reduce infrared radiation, thus making them widely used in high temperature and oxidation environments. [177][178][179][180][181][182][183][184][185] In addition, the microstructure and electromagnetic parameters can be adjusted by controlling the preparation conditions, resulting in excellent performance absorbing materials. Nowadays, ceramic materials commonly used in electromagnetic absorption include silicon carbide, silicon nitride, alumina, alumina borosilicate, and barium titanate.…”
