以炭黑为导电填料，制备导电硅橡胶复合材料，研究导电硅橡胶复合材料的电学性能和力学性能。研究表明，随着炭黑掺量增大，复合材料的体积电阻率（ρ）先快速减小，然后基本稳定。复合材料的邵氏硬度先快速增大，最终趋于稳定，而拉伸强度先增大后减小。炭黑占硅橡胶的质量分数为30%时，复合材料获得最优的综合性能，与未加炭黑相比，ρ降低15个数量级，拉伸强度和邵氏硬度分别提高544.4%和660.0%。

Carbon black was used as a conductive filler to prepare conductive silicone rubber composites, and the electrical and mechanical properties of conductive silicone rubber composites were studied. The study indicates that as the carbon black content increases, the volume resistivity (ρ) of the composites first rapidly decreases and then stabilizes. The Shore hardness of composites first increases rapidly and eventually stabilizes, while the tensile strength first increases and then decreases. When the mass fraction of carbon black in silicone rubber is 30%, the composites achieves the optimal comprehensive performance. Compared with the absence of carbon black, the ρ decreases by 15 orders of magnitude, and the tensile strength and Shore hardness increase by 544.4% and 660.0%, respectively.
