In this study, we used a carbon dot ink to form flexible electrodes on paper. The doctor blade was able to evenly coat the conductive ink on the paper substrate and it was possible to coat large area quickly and simply differently from the other paste ink. Carbon dots with conductivity were used as the main material, SBR (Styrene Butadiene Rubber) was added as a binder, and CMC (Carboxy methyl cellulose) was mixed together as a curing agent. Linear polymer derivatives of cellulose CMC form a three-dimensional cross-linking network through intermolecular hydrogen bonding between the carboxy and hydroxyl groups on the carbon surface. The flexible electrode thus formed has a resistance of about 1.0 to 1.7 KΩ / cm and can be changed by solvent conditions. We have used these electrodes to apply various applications such as touch screens and rollable speakers. |
