Microwave absorption and photocatalytic properties of magnetic nickel nanoparticles/recycled PET nanofibers web

The use of nanoparticles in electrospun web has always been of great interest for a wider and easier application especially for microwave absorption and photocatalytic activity. In this work, nickel nanoparticles/recycled poly (ethylene terephthalate) nanofibers web (Ni NPs/RPET NFs web) were electrospun from a homogeneous sonicated RPET solution containing Ni NPs with an average diameter of 32.5 nm synthesizedthrough the chemical reduction method. To study morphologies, crystalline structure, magnetic, wettability, microwave absorption and photocatalytic activities of the web, field emission-scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), vibrating sample magnetometer (VSM) and electromagnetic properties were used. The saturation magnetization of the Ni NPs/RPET NFs web at a nickel concentration of 3% was 0.5emu/g. In addition, the wettability, the reflection coefficient, the absorption coefficient, the EMI shielding and the photocatalytic activities of the Ni NPs/RPET NFs web were improved compared to the RPET NFs web.
