Defect and interface co-steering ultra-wide microwave absorption and superior thermal conductance of TiO2/Fe/C nanocomposites

Synchronously boosting microwave-absorbing and heat-conducting capabilities in CeO2/Ce(OH)3 core–shell nanorods/nanofibers via Fe-doping amount control

“…Similar phenomena are also found in our previous works. 2,34,42,43 The peak values of μ ′ and μ ′′ are exhibited by 10%Fe-doped CeO 2 /Ce(OH) 3 CSNFs, as shown in Fig. 5b1 and b2.…”

“…7a3). 2,[29][30][31]42,[49][50][51][52][53][54][55][56][57][58][59][60][61][62] Fig. 7b1-b3 illustrate the thermal conduction mechanism of Fe-doped CeO 2 /Ce(OH) 3 CSNFs.…”

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

“…, graphitic carbon. 7 The peak area ratio of the D and the G bands ( S D / S G ) can be utilized to assess carbon crystallinity, i.e. , the smaller the ratio, the higher the crystallinity.…”

“…The third key issue is defect engineering. [7][8][9] High defects can improve electrical insulation and provide more polarization centers for dielectric loss. But the thermal transfers of phonons/electrons are hampered in this case due to the heat resistance produced by phonon-defect scattering.…”

Recent progress in TiO2-based microwave absorption materials

“…Last but not least, combining TiO 2 with magnetic materials (e.g. Fe, 34 Co, 35 Ni, 36 Fe 3 O 4 , 37,38 CoO, 39 and ferrite 33 ) can increase the EM wave loss capacity by increasing the magnetic loss mechanisms. For instance, eddy current loss, natural resonance and exchange resonance will be incorporated into composites.…”
