제목 Dielectric elastomer based on alkylamine-modified MWCNT and its application to touch sensor
초록 The dielectric properties of elastomer-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/MWCNT composites are different depending on the alkyl-chain length of alkylamine. The elastomer composites including MWCNT functionalized with octadecylamine (ODA) exhibit the improved dielectric properties compared to MWCNT modified with hexylamine (HA). We also demonstrate the MWCNT/elastomer composites as a capacitive material of touch sensor and show the effect of MWCNT modified with ODA on the sensitivity of touch sensor.
