Rational molecular design of inorganic polymeric materials for high triboelectric performance |
| 초록 |
Halogenated carbon-based polymers (e.g., PTFE, PVDF) have widely been utilized as extremely negative triboelectric materials. Halogen elements have exceptionally large electron affinity that can accommodate more electrons in comparison with other elements. However, halogen elements are not homopolymerizable. Hence, carbon is introduced to form polymer backbone at the expense of electron affinity. Alternatively, we suggest rational molecular design to synthesize most negative triboelectric polymers using sulfur as a backbone. Triboelectric performance of sulfur-based polymer demonstrated 3-fold increase in both voltages and currents in comparison with a commercial PTFE. |
