| 제목 | Performance enhancement of triboelectric nanogenerators via PVDF/carbon nanocomposite nanofibers |
| 초록 | Recently, wearable devices have a lot of positive influence on human life, but they are also have required as much power in everyday life. Therefore, the energy harvesting is draw attention to its eco-friendly and portable merits. One of the energy harvesting technology is Triboelectric nanogenerator (TENG) that uses surface charged by conjunction of triboelectric effect and electrostatic induction when different materials come into contact. Among the various TENG materials, Polyvinylidene fluoride (PVDF) is one of the most promised materials in the field of TENG due to its high electron affinity and surface charge density. The PVDF has various phases, such as α, β, γ, ε and so on, and shows different TENG performances. Among the various phases, β phase has the highest TENG performances due to its high surface charge density. So, many researchers tried to increasing beta phase for enhancing TENG performance via corona discharge treatment, dielectric nanocomposite. One of the research which used carbon based composite structures, such as carbon nanotube, graphene quantom dot, graphne oxide showed high TENG performance. Herein, we researched β phase changes and TENG performance changes through adding fullerene (C60). In this experiment, electrospun PVDF nanofiber mat was observed with Scanning Electron Microscope(SEM), and β phase changes were analyzed with X-ray Diffraction(XRD).
