The synthesis of SrFe12O19/MWCNT
microwave
absorbent nanocomposites was achieved by using a one-pot hydrothermal
method, resulting in compounds of strontium ferrite nanoplates and
multiwalled carbon nanotube (MWCNT). When the mass ratio of strontium
ferrite to MWCNTs is 6:1, the SrFe12O19/MWCNTs
nanopowder represented the most significant reflective loss of −33.2
dB at 14.11 GHz while the material thickness is 1.48 mm. More importantly,
the nanopowder reaches an efficacious absorbing bandwidth of about
3.96 GHz with a thickness of 1.35 mm, which could lead to a relatively
low mass, thus demonstrating its potential for utilization as a lightweight
and highly efficient wave-absorbing coating. The findings offer a
valuable reference point for the subsequent synthesis of wave-absorbing
materials.
