纤维素作为纳米尺寸自组装单元材料的一颗耀眼明星，具有完美的生物相容性、机械韧性、低密度和强大的改性潜力等特点，所有这些使得纤维素及其衍生物在各种应用中获得了广泛的关注，特别是对于不断扩大的微波吸收（MA）和电磁干扰（EMI）屏蔽市场。本文总结了纤维素及其衍生物在MA和EMI屏蔽方面的最新研究进展，包括最先进的设计理念、合成策略和电磁特性。不同类型的纤维素基电磁元件根据其电磁作用机制（屏蔽或吸收）、填料特性（介电性、磁性或导电性）和结构表达（薄膜或气凝胶）进行分类。分析了其应用带来的好处，为相关研究提供了新颖性和独特的视角。最后，分析了纤维素材料进一步应用的主要障碍和瓶颈，并提出了纤维素材料未来研究的趋势和展望。
Cellulose, a shining star of nano-dimensional self-assembled unit materials, has perfect biocompatibility, mechanical toughness, low density, and powerful modification potential characteristics, all of which make cellulose and its derivatives gained wide attention in various applications, especially for the expanding market for microwave absorption (MA) and electromagnetic interference (EMI) shielding. In this paper, the latest research progresses of cellulose and its derivatives in MA and EMI shielding, including the state-of-the-art design concepts, synthetic strategies, and electromagnetic characters, were summarized. Different types of cellulose-based electromagnetic components have been classified according to their electromagnetic mechanism of action (shielding or absorption), filler properties (dielectric, magnetic or electrical conductivity), and structural expression (film or aerogel). The benefits stemming from its applications are analyzed, providing novelties and unique perspectives for relevant research. Finally, the main obstacles and bottlenecks for further applications were analyzed, and the trend and prospects of cellulose material's future research were proposed.
