To reduce the manufacturing cost of conductive rubber and enhance its engineering applicability，a graphene oxide/silver/polyaniline（GAP）composite was synthesized via an in situ route，and GAP-reinforced electrically conductive silicone rubber was prepared.Characterization by SEM shows that，using graphene oxide as a template，Ag⁺ ions and aniline monomers grew in situ into silver nanoparticles and dendritic polyaniline，forming the GAP composite.The GAP powder disperses effectively within the silicone-rubber matrix to yield a reinforced elastomer.At a loading of 100 phr，the silicone rubber exhibites a tensile strength of 4.67 MPa，an elongation at break of 430%，a tensile modulus of 0.76 MPa，and a volume resistivity of 8.1 mΩ·cm，and comparable to Ag-powder-filled silicone rubber（control values：4.89 MPa，422%，0.72 MPa，and 5.4 mΩcm）.The Shore A hardness of the GAP-reinforced silicone rubber is 64，a 15.8% reduction relative to the Ag-powder-filled counterpart（76）.These results indicate high practical utility for engineering applications，with the prospect of reduced manufacturing costs.
