Surface Modification of Cotton Fabric Using TiO₂ Nanoparticles for Self-Cleaning, Oil–Water Separation, Antistain, Anti-Water Absorption, and Antibacterial Properties

Abstract

Superhydrophobicity is of interest for practical applications such as water repellency, self-cleaning, stain resistance, antibacterial properties, and oil−water separation. In this work, a superhydrophobic coating on cotton fabric is prepared by simple immersion in TiO 2 nanoparticles and perfluorodecyltriethoxysilane solution. Its antiwetting properties, surface morphology, and functionality are characterized. The cotton fabric shows superhydrophobicity with a water static contact angle of 169.3 ± 2.1°and tilt angle of 6.3 ± 2.0°. The coating is also characterized by performing stability tests, and it shows excellent mechanical durability, chemical stability, and thermal stability. Additionally, the water droplet dynamic on the coated surface is also studied. The coated cotton fabric exhibits excellent self-cleaning, stain resistance, rust stain resistance, anti-water absorption, and antibacterial properties. It can also be used in oil−water separation with a high separation efficiency and excellent reusability.

Multi-Hollow Surface Dielectric Barrier Discharge for Bacterial Biofilm Decontamination

“…Such products can enhance biocompatibility and nanoparticle immobilization, and clean and decontaminate various surfaces [ 3 , 4 , 5 ]. Currently, the novel approaches using LTPs are studied to prepare self-cleaning, antibacterial, and biocompatible substrates, especially textiles with smart coatings [ 6 , 7 , 8 , 9 ].…”

A facile preparation of superhydrophobic L-CNC-coated meshes for oil–water separation

“…It is indispensable for superhydrophobic surfaces to meet both the requirements of reasonable rough structures (usually micro-nano layered structure) and low surface free energy. 3 Superhydrophobic surfaces could be fabricated on solid substrates such as wood, 4 metal, 5,6 textile, 7,8 ceramics, 9 and paper 10 via numerous methods such as chemical vapor deposition, 11 sol-gel technique, 12 etching, 13 layer-by-layer assembly, 14 and spraying. 15 The superhydrophobic stainless steel mesh (called "mesh" for short) is an ideal device to solve increasingly severe oil pollution accidents by oil-water separation 16 due to its low cost and high convenience.…”

Development of a microbial coating for cellulosic surface using aloe vera and silane

“…Antimicrobial and antiviral cloth does not only protect the health care worker from of disease but also prevents the growth of fungus on its surface. If cloth is itself anti-wash in nature, then it can also reduce the risk of spread the disease by repelling the body fluid ( Galante et al, 2020 , Tudu, Sinhamahapatra and Kumar, 2020 ).…”
