Interfacial polarization-induced high-k polymer dielectric film for high-performance triboelectric devices |
| 초록 |
Output performance of triboelectric devices depends on the surface charge density that is greatly influenced by the dielectric constant. This study shows that interfacial polarization in bilayer polymer films significantly enhances their dielectric constants, increasing the surface charge density and triboelectric performance. This is the first report of the introduction of interfacial polarization of dielectric materials for the enhancement of triboelectric output performance. The elastic bilayer films consisting of PDMS coated with PTF and PLL as triboelectric pair-materials are utilized in triboelectric devices. It shows an increase in the dielectric constants through interfacial polarization, resulting in enhanced triboelectric performance. We developed a triboelectric temperature sensor with the highest temperature sensitivities among triboelectric sensors and vibration-based nanogenerator providing sustainable power for LED operation without rectification. |
