| 中文摘要: |
| 研究镀银玻璃微珠的用量、粒径、表面改性工艺以及导电硅橡胶硫化程度等对镀银玻璃微珠/硅橡胶复合材料导电性能的影响。结果表明，镀银玻璃微珠的粒径越大，复合材料的导电性能越好；湿法预处理和原位改性-分散工艺制得复合材料的导电性能和导电稳定性优于直接干混工艺；导电硅橡胶硫化程度的提高有利于提高材料的导电性能；Payne效应的大小与导电硅橡胶的体积电阻率有很强的相关性。 |
| 英文摘要: |
| The effects of the addition level，particle size and modification technology of silver-coated glass bead and the curing degree of electrically conductive silicone rubber on the electrical conductivity of silver-coated glass bead/silicone rubber composite were investigated.The results showed that the electrical conductivity of the composite was improved as the particle size of silver-coated glass bead increased；the electrical conductivity and its stability of composite prepared with wet pretreatment or in-situ modification-dispersion were better than those of composite prepared with direct dry-mixing；the electrical conductivity of composite was improved as the curing degree of electrically conductive silicone rubber increased；the Payne effect was highly related to the volume resistivity of electrically conductive silicone rubber. |
