Three-dimensional (3D) flexible foams consisting of reduced graphene oxides (rGO) and in situ grown SiC nanowires (NWs) were prepared using freeze-drying and carbothernial reduction processes. By means of incorporating SiC nanowires into rGO foams, both the thermostability and electromagnetic absorption of the composites were improved. it was demonstrated that rGO/SiC NW foams were thermoz. stable beyond similar to 630 degrees C (90% weight retention in air attnosphere). As expected, rGO/SiC NW foams in the poly(dimethylsiloxane) matrix achieved' effective absorption in the entire X-band (8.2-12.4 GHz) with a thinner thickness (3 mm) in comparison with those of the pure rGO foams. It is revealed that SiC nanowires with abundant stacking faults, twinning interfaces, arid bridged junctions play an important role in the enhanced electromagnetic absorption performance) in addition to the,contribution of interconnected graphene networks. Hierarchical rGO/SiC NW foams not only are efficient absorbers in the critical environments but also can be applied in photocatalytic and thermal -management fields.
