Abstract
This study deals to develop a simple and facile two-step dip-coating method using silver nanoparticles (AgNPs) and fluorine-free silane monomer, 3-(Trimethoxysilyl) propyl methacrylate (TMSPM) for the fabrication of hydrophobic coating on cotton fabric. The anti-wetting properties, surface morphology, chemical composition, and functionality of the cotton fabric before and after modification were well characterized by contact angle measurement, scanning electron microscope (SEM), and energy-dispersive X-ray spectrum (EDX) and FT-IR respectively. The fabricated cotton fabric displays strong durability against different pH solutions, different soft/hard mechanical treatments including adhesive peeling test, abrasion with tissue paper and finger wiping, home laundering, without losing the hydrophobic property. The contact angle values (water contact angle of 148.3 ± 2° and oil contact angle of 0°) imply that the modified cotton has considerable hydrophobic/oleophilic properties. Additionally, the modified hydrophobic/oleophilic cotton fabric exhibits self-cleaning and oil-water separation behavior for both industrial and household importance.
