Specific Properties of Polyester Fabrics Functionalized by RF Plasma and Colloidal TiO2 Nanoparticles

Abstract

This study was aimed to examine the possibility of using RF plasma at low pressure for the surface activation of polyester fabrics in order to improve the binding efficiency of colloidal TiO2 nanoparticles. Colloidal TiO2 nanoparticles were synthesized without stabilizers by acid hydrolysis method. Air and argon were used as plasma gases. Polyester fabrics modified by RF plasma and TiO2 nanoparticles exhibited excellent antibacterial efficiency against E. coli which was preserved after five washing cycles. The presence of TiO2 nanoparticles contributed to a significant increase in UV protection factor (UPF) of fabrics. These values correspond to UPF rating of 50+, which designates the maximum UV protection. Additionally, irradiated polyester fabrics loaded with TiO2 nanoparticles demonstrated satisfactory self-cleaning efficiency.
