Comparison of different synthesis methods for immobilization of magnetite nanoparticles on hydrolysed polyester fabric

Mirjalili, Mohammad

Abstract

Attempts have been made to accomplish synthesis of magnetite nanoparticles and hydrolysis of polyester fabric in onestep. Polyester fabrics are treated in a bath containing ferrous chloride, ferric chloride and sodium hydroxide under threedifferent conditions, namely stirring, ultrasound and high temperature. The successful synthesis of Fe3O4 particles withdifferent shapes on the surface of the polyester fabrics is confirmed by scanning electron microscopy, X-ray diffraction andenergy dispersive X-ray spectroscopy. The treated fabrics are assessed for magnetic, antibacterial and Fenton catalyticproperties. In addition, bending length and water drop absorption time of treated samples are also evaluated. The resultsshow that magnetic, antibacterial and Fenton catalytic activities are superior for samples treated under ultrasound conditionthan the samples treated under stirring or high temperature conditions. Nevertheless, the hydrophilicity and flexibility of thetreated polyester fabrics under various conditions are improved.
