ABSTRACT

This study reported the dual functional self-cleaning PET fabrics prepared from TiO2 and hexadecyltrimethoxysilane treatment, which have photodegradation and superhydrophobicity on the fabric surface. Phodegradation and superhydrophobicity of the resulting fabric were compared with TiO2 or silane treated fabrics. The dual functional self-cleaning PET fabric showed less photodegradation than the TiO2 treated fabric. However, the dual functional self-cleaning fabrics showed superior superhydrophobicity to silane treated fabric with increased water contact angle and significantly decreased rolloff angle. This suggested that the dual functional PET fabric has a great potential to be the commercialized self-cleaning fabric because it is repellent to soil or dust and even if soil or dust is adsorbed on the fabric surface, it can be removed by water rolling off on the surface or photodegradation by the photocatalyst.
