SnO₂ and amorphous carbon were simultaneously introduced onto the surface of multi-walled carbon nanotube (MWCNT) by a simpleand green hydrothermal process followed by heat treatment, finally to obtain the C-SnO₂-MWCNT absorbent with ternary heterostructure. Subsequently, the C-SnO₂-MWCNT/silicone rubber wave-absorbing composites were prepared. XRD, Raman, XPS, SEM, TEM and TGA indicated the C-SnO₂-MWCNT absorbent with ternary heterostructure was fabricated successfully. When the massfraction of C-SnO₂-MWCNT was 30 wt% and the thickness was 2.65 mm, the minimum reflection loss (RLmin) and effective absorption bandwidth (EAB) of the C-SnO₂-MWCNT/silicone rubber wave-absorbing composites could reach -53.5 dB and 3.16 GHz, respectively. Excellent wave-absorbing performance was dueto the synergistic effect of multiple interface & dipolepolarization and conduction loss. Furthermore, the corresponding heat resistance index (T_HRI) of the C-SnO₂-MWCNT/silicone rubber wave-absorbing composites with 30 wt% C-SnO₂-MWCNT reached 209.9 ^oC, higher than that of neat silicone rubber (187.4 ^oC).
