Ternary heterogeneous MWCNT@TiO₂-C wave absorbent was firstly prepared, using glucose, MWCNT, and titanium isopropoxide as raw materials, through the solvothermal process followed by post-heat treatment. Afterwards, MWCNT@TiO₂-C/silicone rubber wave-absorbing composites were fabricated via solution casting and subsequent curing process. XRD, Raman, XPS, and TEM analyses demonstrated the MWCNT@TiO₂-C fillers were successfully synthesized with TiO₂ and amorphous carbon coated on the surface of MWCNT. When the MWCNT@TiO₂-C/silicone rubber wave-absorbing composites contained 25 wt% MWCNT@TiO₂-C fillers and with the thickness of 2.5 mm, it displayed the minimum reflection loss of 53.2 dB and an effective absorption bandwidth of 3.1 GHz. Remarkable wave-absorbing performances for MWCNT@TiO₂-C/silicone rubber composites could be attributed to the synergetic effect of interfacial polarization loss and conduction loss.
