Abstract

In the present study, we developed super-slippery textured surfaces following a simple and effective swelling route using polydimethylsiloxane. For comparison, slippery surfaces using lubricant coating (LC) were also developed. Both slippery surfaces showed low tilting angle (< 5°) and contact angle hysteresis (4°), with high transparency. The textured swollen surface showed lower critical drag velocity (∼ 0.6 m/s) and ice adhesion (∼ 25 kPa) with significant freezing delay (>15 min) than LC owing to effective lubricant entrapment. The stable and persistent lubricating layer on swollen slippery surface endowed long-term immersion, micro cavitation, droplet impacts, and dynamic waves impacts. Results show that texture-swollen surfaces possess a highly effective and persistent super-slippery nature that is potentially useful for many engineering applications.
