摘要
可持续来源的木质素作为富含羟基和羧基等电负性官能团的天然高分子材料,容易获得或失去电子,形成三电效应,从而为制造三电材料提供了巨大的可能性。近年来,人们对木质素制备三电纳米发电机(TENG)进行了广泛的研究。然而,这些方法仍然缺乏明确的分类参考总结。本综述重点介绍了基于木质素衍生材料的 TENG 的前沿研究,并着重强调了木质素的多功能性。综述系统地介绍了基于木质素衍生材料的化学改性、复合增效和表面形态改性方法对 TENG 性能的增强。然后,总结了基于木质素衍生材料的 TENG 目前在能量收集、医疗监测和智能包装等方面的应用。最后,还综述了基于木质素衍生材料的 TENG 在未来发展中面临的挑战和策略。因此,本综述将鼓励利用木质素衍生材料制造生态友好型 TENG,这些材料在能源转换领域具有广阔的应用前景。
Lignin-derived materials for triboelectric nanogenerators with emphasis on lignin multifunctionality
Sustainably sourced lignin, as natural polymer material rich in functional groups with electronegativity such as hydroxyl and carboxyl groups, is prone to gain or lose electrons to form triboelectric effects, thus providing enormous possibilities for the fabrication of triboelectric materials. Lignin has been extensively investigated in recent years for the preparation of triboelectric nanogenerators (TENG). However, there is still a lack of a well-defined classification references summarizing for these approaches. This review highlights the forefront research studies on TENG based on the lignin-derived materials with accented emphasis on lignin multifunctionality. A systematic description of the enhancement of TENG properties based on the lignin-derived materials by chemical modification, composite synergy and surface morphology modification methods is presented. Then, the current applications of TENG based on the lignin-derived materials, such as energy harvesting, medical monitoring and smart packaging, are summarized. Finally, challenges and strategies for the prospective development of TENG based on the lignin-derived materials are also reviewed. Therefore, this review will encourage the utilization of lignin-derived materials for the fabrication of eco-friendly TENG with promising applications in the field of energy conversion.
