Flexible electric conductive thin films were prepared by simply spray coating on a polyethylene terephthalate (PET) film. The used conductive ink was aqueous nanocomposite based on single-walled nanotubes (SWNT) packed by cellulose nanofiber (CNF). The cellulose molecule offered a highly packed nano-wire form of CNTs and made an aligned morphology of CNT-CNF nanocomposite by the inter-, intramolecular hydrogen bonds of CNFs. The further stable coating produced by UV treatment that the PET was exposed for 10 min at room temperature. The UV treatment was offering to the anchoring of CNT-CNF nano-wires on the surface of PET by the formation of polarity and was also used to the curing of photoresist. As a result, the electrical stability of the electrode as a nanocomposite thin coatings was increased successfully under mechanical deformation such as twisting and stretching. It was observed that altering morphology from coating processing and UV treatment related to our results. In this study, the morphology of the CNT-CNF nanocomposite coating electrode was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), dynamic mechanical analysis (DMA) and 3D laser scanning confocal microscopy. |
