Novel SiBCN composite fibers with broadband and strong electromagnetic wave absorption performance

Enhanced electromagnetic wave absorption properties of SiCN(Ni)/BN ceramics by in situ generated Ni and Ni3Si

“…2 showing the D peak at 1350 cm −1 representing sample disorder while the G peak at 1580 cm −1 represents graphitization degree. 15 In general, the value of I D / I G represents the degree of disorder or graphitization in the sample. 16 The introduction of Ni has a great influence on the carbon structure of the sample.…”

Research on Electromagnetic Wave Absorption Based on Electrospinning Technology†

“…The minimum reflection loss value of SiBCN nanofibers is −54.91 dB, and the maximum effective absorption bandwidth is 4.72 GHz (Figure 13). [ 59 ]…”

Boosting electromagnetic wave absorption of Ti 3AlC 2 by improving effective electrical conductivity

“…This is because dielectric loss (conduction loss and polarization loss) is the dominant electromagnetic wave loss mechanism for these high-temperature EMA materials, while the magnetic loss ability will be lost at a temperature higher than Curie point [8,9]. In recent years, non-oxide ceramics such as SiC [6,[10][11][12], SiBCN [13][14][15][16], and Si 3 N 4 [17][18][19][20] and oxide ceramics such as BaTiO 3 [21,22] and Mn 2 O 3 [23,24] have attracted widespread attention in both academia and industry due to their excellent polarization loss properties. Poor conduction loss is a typical issue with this sort of material since it is challenging to create a sufficiently strong conductive network in the ceramic matrix.…”
