| 英文摘要 | Effective thermal shielding materials with perfect anti-ablation and mechanical performances play a pivotal role of protecting aircraft suffering harsh conditions. with graphene oxide (go) and nano-silicon spheres as raw material, a layered si/go precursor film was prepared by filtration, followed by in-situ carbothermal reaction to obtain the composite film of sic and graphene (sic/g film). the as-obtained material shows a sandwich-like anisotropic structure, with excellent anti-ablation performance in ablation experiment. the film exhibit a high mechanical stiffness with hardness and elastic modulus of 0.56 and 3.40 gpa, respectively. besides, in-and out-plane thermal conductivity are 27.98 and 0.15-0.23 wm(-1) k-1, respectively. in the film, the orientated graphene sheets are not only the scaffold to retain the integrity of the film, but also improve in-plane thermal dissipation efficiency. meanwhile, in-situ grown sic particles act as the major anti-ablation functional layer, as well as the interlayer spacer to retard the heat transfer perpendicular to the film. therefore, this novel sandwich-like structure composed by sic and graphene layers could offer great protection from multiple ablation shocks in many fields.
