Dielectric elastomer based on multi-walled carbon nanotubes modified with alkylamine |
| 초록 |
The dielectric properties of polymer- based composites with high dielectric fillers have been intensively examined for a variety of potential applications, including dielectric elastomer actuators, capacitive touch sensor and embedded capacitor materials. In this study, we modified multi-walled carbon nanotubes (MWCNT) with alkylamine in order to improve their dispersibility in solvent and elastomer matrix. We demonstrate that the dispersibility and dielectric properties of elastomer/MWNCNT composites are different depending on the alkyl-chain length of alkylamine. The elastomer composites including MWCNT functionalized with octadecylamine exhibit the dielectric constant of 10 and dielectric loss of 0.18(at100Hz) at 0.5wt% filler content in matrix, which are the improved properties compared to those of elastomer/MWCNT composites without alkylamine(dielectric constant: 2.6 and dielectric loss: 0.035 at 100Hz and 0.5wt%) |
