Microwave properties of epoxy composites with mixed filler carbon nanotubes/BaTiO3

Hierarchically Multifunctional Polyimide Composite Films with Strongly Enhanced Thermal Conductivity

“…The EMI SE of PI composite films and other materials based on graphite derivatives and magnetic substances is summarized in Fig. 4 f [ 16 , 47 – 60 ]. It can be seen that the PI composite films prepared in this work has a relatively high specific efficiency (the ratio of EMI SE to the effective thickness of the material, and the effective thickness of PI composite films for EMI shielding is about 85 μm), which is about 400 dB mm −1 .…”

BaTiO3@C Core–Shell Nanoparticle/Paraffin Composites for Wide-Band Microwave Absorption

“…In practical applications, the features of broad EAB, stability, and lightweight are the key considerations. Figure gives the comparison of the thickness and the EAB of the BaTiO 3 -based absorbers in recently reported papers. ,,− As can be seen, the BaTiO 3 @C/paraffin composite in this work exhibited a broad EAB of 6 GHz at a thickness of only 1.8 mm, which is the highest among all of the BaTiO 3 -based absorbing materials listed. Generally, the absorption properties of the EM wave of a material depend on both the impedance matching and attenuation characteristics that are closely related to its microstructure and the EM properties. − Figure illustrates the microwave dissipation process of the BaTiO 3 @C/paraffin composites in the present work.…”

Recent advancements in the electromagnetic interference shielding performance of nanostructured materials and their nanocomposites: a review

“…Dielectric materials and their composites have also been used in blocking incoming EM waves. 406–437 Lu et al 406 studied the thickness dependence variation of reflection loss against ε ′ and ε ′′ (Fig. 18(a)) and microwave absorption properties of the composites loaded with 10 wt% ZnO@MWCNTs vs. the frequency and thickness at different temperatures (Fig.…”
