Phase-Separation Strategy for Synthesis of Extremely Negative Triboelectric Polymeric Sulfur Blends |
| 초록 |
Since the introduction of triboelectric nanogenerators (TENG), halogenated carbon-based polymers have widely been chosen as one of the most negative triboelectric materials due to the high electron affinity property of halogen atoms. Herein, we report a facile synthesis of extremely negative triboelectric polymers by blending fluorine-rich poly(2,3,4,5,6-pentafluorostyrene) (PPFS) along with polymeric sulfur, which can exceed triboelectric performance of conventional halogenated carbon-based polymers. PPFS is added in-situ during the inverse vulcanization of elemental sulfur along with 1,3-diisopropenylbenzene (DIB) crosslinker. Ground polymer blends were hot-pressed into films, which result in a phase separation of PPFS from sulfur copolymers to the hydrophobic air-interface. The surface localized PPFS molecules resulted in a long-term stable 8-fold and 9-fold increase in triboelectric voltages and currents, respectively, in comparison with commercial PTFE. |
