Fabrication of Superhydrophilic Polyester Fabrics Using Various TiO₂Colloidal Dispersions

Abstract

The purpose of this research was to apply four stable colloidal dispersions, combining dierent TiO2 coreshell nanoparticles, onto polyester fabric, according to exhaustion procedure, in order to enhance fabrics' water and moisture absorption properties. Firstly, all colloidal dispersions were analysed using transmission electron microscopy (TEM) and dynamic light scattering (DLS) and secondly, the morphologies of TiO2 modied PES surfaces were evaluated by scanning electron microscopy (SEM). In addition, the superhydrophilic character of brous surfaces was investigated by water contact angle measurement. For this purpose, dynamic tensiometry was employed by measuring the changes in the net force on a surface during the repeated immersion and emersion of a solid into a probe liquid. The obtained results show excellent wettability of TiO2 upgraded PES fabrics depending on the type of applied nano-sized TiO2-hybride.
