Abstract

The Ag-decorated poly(vinyl alcohol) (PVA) composite nanofibrous webs incorporating Fe ₂O ₃ nanoparticles were fabricated by electrospinning and metal-deposition methods for electromagnetic interference (EMI) shielding applications. The Ag-decorated PVA/Fe ₂O ₃ composite nanofiber webs with various Ag thicknesses and different amounts of Fe ₂O ₃ nanoparticles were prepared and used for EMI shielding measurement. For the EMI SE measurement, a near-field antenna measurement system was used. The measurement of EMI SE was carried out at the frequency range from 0.5 to 18 GHz, and the electromagnetic parameters were measured. The morphologies and microstructures of the resultant PVA/Fe ₂O ₃ composite nanofiber webs were characterized using field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM), respectively. The effects of surface morphologies and Fe ₂O ₃ nanoparticles on the EMI shielding effectiveness of Ag-decorated PVA/Fe ₂O ₃ composite nanofiber webs were investigated.
