A simple immersion method is proposed to develop durable superhydrophobic cotton fabric from low-cost, fluorine and silane-free eco-friendly materials, address the growing environmental concerns led by hazardous surface modifiers. Herein, silica sand nanoparticles (SS NPs) were synthesized mechanical ball-milling approach, a least reported abundant natural source, Cherthala sand. small town in Alappuzha district of Kerala noted for its high quality with 96.5% silica. The synthesis SS NPs was optimized based on ball-to-powder weight ratio (BPR) milling time using Central Composite Design response methodology. Minimum crystallite size (∼26 nm) maximum turbidity (355 NTU) obtained trial loaded 20:1 BPR processed 10 hours. In traditional nano-coating milled NP employed as roughness-enhancer along polymeric binder adhesion; silicone oil stearic acid lower energy. standardized coating mixture exhibited water contact angle 158.9 ± 7.6°, long-term repellency, chemical stability after 12 hours standing acidic alkaline pH more than five detergent washing cycles. coated fabrics resilient O2-plasma, UV-irradiation adhesive peel test. study also presented practical scope developed coatings oil-water separation wearable smart textiles. Thus, present work offers scalable sustainable route NP-based functional textiles same comfort, touch-proof, breathability.
