Abstract: Absorptive materials, by absorbing electromagnetic wave energy, effectively mitigate electromagnetic interference through the reduction or elimination of wave reflection.The electromagnetic parameters of materials determine their electromagnetic wave absorption performance.Traditional control strategies, such as adjusting the filler ratio, changing macroscopic morphology, and composite methods, have certain limitations and cannot fundamentally alter the electromagnetic parameters, hindering their further development.Micro-nanostructure design strategies can fundamentally change the electromagnetic parameters of materials by altering their electrical conductivity, charge density, and magnetic properties.This approach demonstrates significant advantages in controlling electromagnetic wave absorption capacity.However, the difficulty of precise micro-nanostructure design and restrictions on mass production pose challenges to its development.Additionally, comprehending the structure-property relationships between these micro-nanostructures and electromagnetic wave response and loss mechanisms still poses significant challenges.Herein, a comprehensive review of the structure-property relationships between micro-nanostructures and electromagnetic performance is presented, elucidating the absolute advantages of micro-nanostructure design strategies in regulating electromagnetic wave absorption capacity.Moreover, through strategies such as element doping, surface effects modulation, and nucleation-controlled growth, the paper delineates the impact of micro-nanostructure changes on electromagnetic response and loss mechanisms, providing researchers with strategic insights and theoretical guidance for modulating electromagnetic properties through micro-nanostructure design.Finally, using quantum dots, nanocrystals, and nanowires as typical examples, summarizing the mechanisms, strategies and advantages for regulating electromagnetic parameters, and the current research status and prospects in the field of electromagnetic absorption, providing a theoretical foundation and strategic support for the development of micro-nanoparticles in the electromagnetic wave absorption field.
