Enhancement of electrical and dispersion properties of MWCNT nanocomposites in PEDOT:PSS by non-covalent functionalization with salt type modifier |
| 초록 |
In this study, different types of salt modifiers having pyrene (P4AS), anthracene (A2AS, A3AS) and naphthalene (N2AS) were synthesized to functionalize the surface of MWCNTs by a non-covalent method. PEDOT:PSS/functionalized MWCNT nanocomposite solutions were prepared by chemical oxidative polymerization. Dispersibility and dispersion stability of PEDOT:PSS/MWCNT solutions were improved with the salt modifier than pristine. Dispersion of PEDOT:PSS/MWCNT solutions with salt modified MWCNT(no sediment even after 20weeks) were much more stable than pristine(sediment formed after 12weeks). The electrical properties of nanocomposite films prepared from PEDOT:PSS/MWCNT solutions were investigated depending on the type of salt modifier by 4-point probe method. The electrical properties of PEDOT:PSS/salt modified MWCNT nanocomposites will be further discussed in detail. |
