| 通过导电炭黑与多壁碳纳米管（MWCNT）并用制备丙烯酸酯橡胶（ACM）柔性电极材料，研究导电炭黑和MWCNT在ACM基体中的分散性及其并用比对柔性电极材料硫化特性、物理性能和导电性能的影响，并分析柔性电极材料与介电弹性体（DE）基体的粘合性能。结果表明：导电炭黑和MWCNT在ACM基体中具有良好的分散性；添加导电炭黑/MWCNT并用体系的ACM柔性电极材料的拉断伸长率远大于200%，满足DE发电机对于大形变的要求，且与仅添加导电炭黑的柔性电极材料相比，其硬度和弹性模量减小，柔韧性提高；随着MWCNT用量的增大，柔性电极材料的导电通路逐渐完善，导电性能提高；导电炭黑/MWCNT并用比为10/10的ACM柔性电极材料与ACM基DE基体共硫化后，两者的粘合强度达到5 N·mm-1，且粘合稳定性较好。 |
| 英文摘要: |
| Acrylate rubber （ACM） flexible electrode composites were prepared by the blend of
conductive carbon black and multi-walled carbon nanotubes（MWCNT），the dispersibility of conductive
carbon black and MWCNT in ACM matrix and the effects of their blend ratios on the vulcanization
characteristics，physical properties and electrical conductivity of the flexible electrode composites were
investigated，and the adhesion of the flexible electrode composites and dielectric elastomer（DE） substrates
was analyzed. The results showed that conductive carbon black and MWCNT had good dispersibility in the
ACM matrix. The elongation at break of the ACM flexible electrode composites with conductive carbon
black/MWCNT blend system was much greater than 200%，which met the requirements of the DE generator
for large deformation. Compared with the flexible electrode composites with conductive carbon black，the
hardness and elastic modulus of the flexible electrode composites with conductive carbon black/MWCNT
blend system were reduced，and the flexibility was improved. With the increase of the amount of MWCNT，
the conductive path of the flexible electrode composites was gradually improved，and the conductivity
increased. After co-vulcanization of ACM flexible electrode composites with 10/10 blend ratio of conductive
carbon black/MWCNT and ACM-based DE substrates，the adhesive strength of the two reached 5 N·mm-1，
and the bonding stability was good. |
