Abstract
Highlights
A mild 2,2,6,6-tetramethylpiperidine-1-oxide mediated modification system was applied to improve the reactivity and introduce porous structure of cellulose fiber skeleton.
在一个技术进步与可持续发展相融合的时代，开发多功能集成的可再生材料的需求越来越大。这项研究通过将能量存储、多波段电磁干扰（EMI）屏蔽和结构设计集成到生物基材料中，填补了一个关键的空白。具体来说，在2,2,6,6-四甲基哌啶-1-氧化物（TEMPO）氧化的纤维素纤维骨架内形成导电聚合物层，其中温和的TEMPO介导氧化系统赋予其丰富的大孔，可以用作活性位点（比表面积为105.6 m2 g-1）。得益于纤维素纤维衍生复合材料特殊的分层多孔结构，该复合材料在5 mA cm-2条件下可实现12.44 F cm-2的高面比电容和3.99 mWh cm-2 （2005 mW cm-2）的面能密度，在50 mA cm-2条件下10,000次循环后仍保持90.23%的优异稳定性。同时，复合材料的电导率高达877.19 S m-1，在多个波段具有良好的电磁干扰效率（> 99.99%）。该复合材料在L、S、C、X波段的电磁干扰值均超过100db，可有效屏蔽日常生活中的电磁波。提出的策略为在储能和电磁干扰屏蔽等应用中利用生物基材料铺平了道路，为更可持续的未来做出了贡献。
期刊介绍：
Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand.
Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields.
Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
