Deposition of iron oxide nanoparticles on glass mat using DC magnetron sputtering method-magnetic properties

Abstract

Magnetic nanoparticles have important applications in industrial textiles and can be used as filters for separating color and heavy metals from factory wastewater. One of the most important magnetic materials is iron oxide(Fe3O4). In this research, different sputtering systems were used for depositing iron oxide nanoparticles on the surface of the glass mat. Three-angle sputtering machine, DC sputtering, and DC magnetron sputtering were used for the deposition of Iron Oxide nanoparticles. Deposition of Iron oxide nanoparticles with three angel and DC sputter systems was not satisfactory, as the rate of sputtering is very low in these machines. Therefore, these two methods were discarded and the study was performed on the next method. The results related to DC magnetron sputtering were satisfactory. The glass mat was deposited by Iron Oxide with different exposure times of 2, 3, and 4 h. The thickness of the layer, structural shape, and existing elements on the surface, were investigated using different analytical instruments. The magnetic properties of deposited fabrics were studied with a vibrating-sample magnetometer (VSM) and photocatalytic properties were also discussed.
