Enhancing electromagnetic wave absorption performance through co-regulation of microstructure and spatial orientation of RE-Ni MOF

The enhancement of electromagnetic wave absorption performance hinges on the intricate evolution of morphology and topology within MOF-derived materials—an issue of paramount significance in the electromagnetic wave absorbing arena. Here, by skillfully modulating multi-dimensional micro-nano structures and orchestrating the asynchronous orientation of nano-sheets across micro–macro dimensions, a more intricate microstructure and magnetoelectric loss mechanism for MOF-based absorbers are cultivated. In tandem, advanced high-frequency simulation software is harnessed to dissect the material's magnetoelectric loss mechanism and substantiate its tangible Far-field microwave absorption capacity. Our study not only pioneers a novel exploration space within the realm of microwave-absorbing materials but also introduces an innovative paradigm, where multi-scaled orientation and microstructural co-regulation converge to enhance electromagnetic wave absorbing properties.
