This study presents the synthesis, characterization, and evaluation of stearic-acid-coated sand (SACS) as a superhydrophobic material for agricultural water management applications. The fabrication process involves coating silica particles with stearic acid in an ethanol-based solution, followed by controlled drying to achieve stable uniform hydrophobic layer. Structural, chemical, physical characterizations confirmed successful functionalization surface. coated exhibited high contact angle (WCA > 150°), indicating strong repellency potential reducing loss soil systems. Experimental results demonstrated enhanced moisture retention SACS-treated soil, prolonging availability up four additional days compared untreated samples. Despite its promising performance, degradation under acidic or organic solvent exposure remains concern long-term application. Overall, this work SACS low-cost, scalable solution improve conservation dry areas, supporting sustainable farming practices.

Superhydrophobic surfaces are renowned for their extreme hydrophobicity and versatility, showing great potential in numerous applications. Yet, the complexity of production susceptibility to mechanical chemical degradation significantly limit practical use. Herein, we introduce a straightforward one-step, solvent-free method situ growth polysilsesquioxane nanospikes (PNS) on glass microfibers, creating hierarchical micronano composite material with excellent superhydrophobic properties, evidenced by water contact angle approximately 170° rolling below 3°. This exhibits exceptional stability against severe temperatures, humidity, corrosive substances, including strong acids/bases organic solvents, maintaining its superhydrophobicity even after repeated abrasion oil contamination. Such resilience is attributed synergistic effect structure three-dimensional, covalently cross-linked PNS. Notably, it can easily rapidly transform between superhydrophilic states via simple plasma treatment surface re-engineering, facilitating application highly efficient (>98%) separation diverse complex oil–water mixtures. work opens promising avenues applying superwettable scenarios, especially those demanding durability adaptability.
