Rational Molecular Design of Polymers Towards Extremely Negative Triboelectric Materials |
| 초록 |
Halogenated carbon-based polymers (i.e. PTFE, PVDF) have widely been utilized as extremely negative triboelectric materials. While halogenic elements are employed for their larger electron affinity (-270 ~ -349 kJ/mol) to accommodate more electrons for triboelectric generation, carbon is being introduced to provide polymer backbone at the expense of electron affinity. In this study, we report rational molecular design of polymers to exceed the triboelectric generation performance by using inorganic element as a polymer backbone. We demonstrated 4-fold increase in triboelectric performance in voltages and currents with the novel inorganic polymers in comparison with a commercial PTFE. Complete with a sole layer of the inorganic polymer with Al electrodes, the triboelectric open-circuit voltage reached 1360 V and demonstrated direct powering of 630 LEDs under the minimal force of ~30 N. |
