Synthesis and electromagnetic shielding performance of nickel nanowires with controllable morphology

Nickel nanowires (NiNWs) were synthesized by a simple hydrazine hydrate reduction method. The morphology of NiNWs was controlled via adjusting the molecular weight and amount of polyvinylpyrrolidone (PVP). To demonstrate practical application, NiNWs filled PVDF (NiNWs/PVDF) film was prepared and measured. The result shows that shielding effectiveness (SE) is up to 43 dB for the film with 9 wt% NiNWs (8.2-12.5 GHz), suggesting its great potential application in EMIS for today electronics.
