Abstract

White-fungus-like NiS_x microspheres have been synthesized on a large scale by using a simple hydrothermal method. The influence of the reaction time and the surfactant on the final products was investigated, and the formation mechanism was discussed. The synthesized white-fungus-like NiS_x microspheres were used firstly as fillers in the fabrication of NiS_x /polyvinylidene fluoride (PVDF) composites. Relationships between the loadings of the NiS_x and wave-absorption properties of the composites were analyzed. The loss mechanisms of NiS_x /PVDF with different loadings were also discussed according to their dielectric and magnetic behaviors.

Keywords: absorption; nanostructures; nickel; organic-inorganic hybrid composites; polymers.
