Description
Summary: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. [Display omitted] •Extensive research works on cellulose derivative composites for MA and EMI shielding are demonstrated.•Cellulose-based aerogels and films with unique electromagnetic interactions are specifically highlighted.•Current bottlenecks and future trends of cellulosic materials for MA and EMI shielding are objectively evaluated.•Microwave loss and shielding mechanisms are systematically reviewed.
