A Flexible Electromagnetic Interference Shielding Nanocomposite Film Based on Cellulose Nanofiber and Graphene Nano Plate |
| 초록 |
A flexible electromagnetic interference (EMI) shielding nanocomposite film is prepared using graphene nano plate (GNP) and cellulose nanofiber (CNF) and its structural, mechanical, and electrical properties are characterized in this study. A water-soluble self-dopped conducting polymer (WSC) as a functional surfactant is synthesized to enhance the dispersibility of GNP in water phase. CNF as a matrix and poly (ethylene glycol) (PEG) as a polymeric binder are added to the aqueous solution containing exfoliated GNP by WSC and the flexible EMI shield nanocomposite film is prepared using the mixed solution. The resulting EMI shielding film shows outstanding flexibility and excellent EMI shielding performance. This is attributed to the uniform distribution of GNPs in the matrix and the unique multiple layered structure of GNPs induced by CNFs. |
