| Abstract Scope |
A coating-free superhydrophobic glass surface was engineered on soda-lime glass using UV nanosecond laser texturing, followed by low-temperature heat treatment. The laser texturing process generates hierarchical surface structures that combine micro-, submicron-, and nanoscale features. Pristine soda lime glass is inherently superhydrophilic (contact angle <10°) due to the abundance of surface oxides and hydroxyls. Laser texturing introduces surface roughness, followed by heat treatment, which reduces surface energy through dehydroxylation and subsequent ambient organic adsorption. The engineered surface exhibits a water contact angle of 155° (±1.8°), a roll-off angle of ~3 (±1.5°), hysteresis of 4.94° (± 1.30°), and an optical transmittance of ~60%. SEM and XPS analyses confirm the formation of hierarchical morphology and chemical modification, which are responsible for the durable superhydrophobic behavior. The optical transparency was evaluated using a UV-visible spectrophotometer. This scalable and environmentally sustainable approach provides a cost-effective method for fabricating coating-free superhydrophobic glass, maintaining optical functionality. |
