The three-dimensional (3D) MoS2 hierarchical nano spheres 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 MoS2 nanospheres compounded with polyvinylidene fluoride (PVDF) were investigated in a broad frequency range of 2-40 GHz. The results indicated that the MoS2/PVDF nanocomposites possess adjustable and enhanced wave absorption performance. Furthermore, the MA performance can be effectively, tuned by, he absorber's thickness and filler content. In addition, the peculiar hierarchical nanostructure of MoS2 is beneficial :to microwave absorption property compared with the bulk MoS2 and micrometer-sized MoS2. Moreover, the main microwave absorption mechanism including various polarization, destructive interference theory, and multiple reflection has been described in detail.
