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

Abstract

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