中文摘要 本成果實現用於能量收集摩擦納米發電機和自供電可穿戴電子設備的自修復、高度可拉伸和抗凍的超分子凝膠。
自修復且有廣泛工作溫度的能量收集設備是自給自足電子產品的挑戰。本研究報導了一種可自修復、可拉伸和抗凍的完全凝膠基摩擦納米發電機，其工作溫度範圍為 - 40 至 80 °C。這些凝膠網絡是通過可逆物理鍵的超分子相互作用構建的，能夠提供高達 50 倍應變的高拉伸性和快速自愈性（電極凝膠為 4 分鐘，摩擦層凝膠為 24 小時）。即使在 5000 次循環操作後仍保持優異性能，並在多次切割/自修復過程後表現出穩定的性能。此外，能量收集能力可用於 - 40 至 80 °C。
英文摘要 Deformable energy-harvesting devices that are self-repairable and possess broad working temperatures remain a challenge for autonomous flexible electronics. Herein, the self-healable, stretchable, and anti-freezing entirely gel-based triboelectric nanogenerator (TENG) with a wide working temperature range from − 40 to 80 °C is reported in this study. Initially, an electrode gel was prepared by mixing poly(lipoic acid) with supramolecular crosslinkers of Fe3 and phytic acid (PA), and the conductive polymer poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) was added. Secondly, a triboelectric gel was synthesized using amino- and hydroxy-terminated poly(dimethylsiloxane) (PDMS) along with isophorone diisocyanate and silicone oil. These gel networks were constructed by supramolecular interactions of reversible physical bonds and able to contribute high stretchability up to 50 times strain with fast self-healability (4 min for electrode gel and 24 h for tribolayer gel). The resulting gel-based TENG maintained excellent performance even after 5000 cyclic operations and showed stable performance after multiple cut/self-healing processes. Its outputs were increased as it was biaxially stretched up to 150% strain to retain its elasticity, ensuring its applicability in flexible uses. Moreover, the energy-harvesting capability was verified to be applicable from − 40 to 80 °C. Last, the gathered energy from the gel-based TENG was demonstrated to power up commercial electronics.
