| Abstract: |
| 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. |
