The textured swollen surface showed lower critical drag velocity (∼ 0.6 m/s) and ice adhesion (∼ 25 kPa) with significant freezing delay (&gt;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.

The sensor utilizes Single-Walled Carbon Nanotubes (SWCNTs) functionalized with 2,2,6,6-tetramethylpiperidin-1-oxyl (TEMPO) to enhance sensitivity. The fabrication process involves a straightforward method for forming the sensor surface, demonstrating the deposition of SWCNTs using a drop-coating technique.
