• It is critical to develop a new method to prepare engineered carbon‐based fillers for high‐performance applications. In this article, the functional nanocarbon‐based fillers (FG‐M) composed of multiwalled carbon nanotubes (MWNTs) and graphene oxide (GO) was synthesized by a simple self‐assembly reaction under the existence of triethoxyvinylsilane. Based on the FG‐M fillers, the silicone foam composites (FG‐M/SF) were prepared, and the electrical, thermal, and mechanical properties of the composites were studied. Results showed that the FG‐M could effectively improve the electrical, thermal, and mechanical properties of the composites compared with the single‐filler system (GO/SF and MWNTs/SF). Especially, the composites exhibited the best synergistic effect on electrically, thermal and mechanical enhancement while the ratio of MWNTs and GO was close to 1:1. Moreover, the effect of type and content of fillers on the rheological properties and density of the composites was also studied. The result showed that the FG‐M/SF system has good thixotropic and foaming performance. The FG‐M filler will have a good application prospect in the preparation of high‐performance SF composites.
