Preparation and characterization of CTAB surfactant modified TiO₂ nanoparticles as antibacterial fabric coating material

Abstract

TiO2 preparation has been carried out with the addition of cetyl trimethyl ammonium bromide (CTAB) surfactant. The sol-gel method is used in the preparation of TiO2, where TiCl4 is used as a precursor. The resulting TiO2 was characterized using XRD, FTIR, XRF and SEM. XRD results show the crystal size of TiO2 17.75 nm with the rutile phase. The FTIR results show a broad absorption band between 800 and 400 cm−1 by Ti–O vibrations in the crystal lattice. The XRF results showed that the TiO2 content was 80.80%. Morphological results showed an irregular ball-like structure that was less aggregated. The characterization results show that TiO2 can be used as a coating on fabrics with antibacterial properties.

Nanoparticles of metal/metal oxide embedded fabrics to impart antibacterial activity to counteract hospital acquired infections

“…As per the literature reports the fabrics functionalized with TiO 2 NPs have better antibacterial and physical properties [105]. Bukit et al [106] reported that the TiO 2 NPs prepared by sol-gel technique and functionalized with CTAB can be used as antibacterial material to be coated over fabrics. Also, it was reported that the TiO 2 NPs modified fabric displayed excellent antibacterial activity against both gram positive and gram negative bacteria owing to its catalytic activity.…”

A review focused on the superhydrophobic fabrics with functional properties

“…The electrons are excited to the conduction band from the valence band leading to the generation of electron/ hole pair, and they consequently react with H 2 O and O 2 to generate ROS. 137,138 Singh et al 139 developed SH cotton fabric using polytriethoxyvinylsilane and polydimethylsiloxane along with AgBr NPs. The SH property was promoted by polytriethoxyvinylsilane and polydimethylsiloxane whereas the photocatalytic activity was induced by the presence of AgBr semiconductor.…”

“…When the light with suitable energy is irradiated over the photocatalyst present on the SH surface, redox reactions occur. The electrons are excited to the conduction band from the valence band leading to the generation of electron/hole pair, and they consequently react with H 2 O and O 2 to generate ROS 137,138 .
