Flexible, free-standing polyaniline-intercalated graphene sheet films for electrochemical sensor electrodes |
초록 |
Nanostructured materials are beneficial for sensor application because they have high surface-to-volume ratio and small dimensions. In this work, conductive and soluble polyaniline (PANI) was prepared through the combination with three organic additives as a ternary dopant for achieving both electrically conductive and adhesive properties. Graphite was spontaneously exfoliated by conductive PANI-glue, which resulted in the formation of random-alternating layered graphene/PANI (G-PANI) nanoarchitectures. The sensing performance of the G-PANI electrode depended on the type of dopant employed, and more importantly, the unique geometrical composition of the nanoarchitecture gave rise to anisotropic electrical properties. A series or parallel connection-like configuration of the intercalated PANI nanolayers was formed when a voltage was applied perpendicular or parallel to the stacked graphene plane. |
