The three-dimensional (3D) MoS 2 hierarchical nanospheres which assembled spontaneously by two-dimensional (2D) lamina have been successfully designed and fabricated in large scale via a simple hydrothermal process. Subsequently, the electromagnetic wave absorption properties of hierarchical MoS 2 nanospheres compounded with polyvinylidene fluoride (PVDF) were investigated in a broad frequency range of 2–40 GHz. The results indicated that the MoS 2 /PVDF nanocomposites possess adjustable and enhanced wave absorption performance. Furthermore, the MA performance can be effectively tuned by the absorber’s thickness and filler content. In addition, the peculiar hierarchical nanostructure of MoS 2 is beneficial to microwave absorption property compared with the bulk MoS 2 and micrometer-sized MoS 2 . Moreover, the main microwave absorption mechanism including various polarization, destructive interference theory, and multiple reflection has been described in detail.
