摘要

With the advancement of functional textiles, superhydrophobic fabrics have garnered significant attention due to their excellent waterproofing, stain resistance, and self-cleaning properties. However, their application has been limited by complex preparation processes, high costs, and the tendency to lose hydrophobicity during daily use. This study employed a simple, economical, and durable approach. Specifically, the polyester (PET) fabric was treated with a modified sol–gel containing materials prepared from perfluorodecyltriethoxysilane(PFDTES), KH560, and silica nanoparticles via dip-coating and heat curing processes. The treatment conditions were optimized to fabricate the fabric with robust superhydrophobicity and chemical durability. Fourier Transform Infra-Red (FTIR), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) analyses were conducted to verify the morphology, rough structure and elemental analysis of modified fabric surfaces, respectively. It demonstrated that the modified fabric achieved a water contact angle of 157.0°. It exhibited exceptional physicochemical durability under mechanical abrasion (300 cycles), repeated washing (30 cycles), and harsh chemical exposure (pH = 1 or 13). In addition to outstanding self-cleaning and stain resistance, the modified fabric also showed remarkable chemical corrosion resistance. This superhydrophobic fabric showed great potential for broad applications across various industries, overcoming the limitations of current superhydrophobic materials.
