Lotus Effect: Nanotextured Self-Cleaning Surfaces
Compare a smooth hydrophilic surface against a nanotextured lotus-leaf surface in the Cassie-Baxter state: watch droplets spread and stay put versus ball up, roll off at a shallow tilt, and sweep dirt away as they go.
A side-by-side 3D comparison of a smooth hydrophilic surface and a nanotextured, Cassie-Baxter-state lotus surface. Tilt the rig, drop water, and watch how nanoscale pillar texture — not surface chemistry alone — decides whether a droplet spreads and stays or balls up, rolls off at a shallow angle, and sweeps dirt away with it.
Compare a smooth hydrophilic surface against a nanotextured lotus-leaf surface side by side in 3D: on the smooth panel droplets wet and spread flat, leaving dirt undisturbed, while on the nano-pillared panel droplets sit in the Cassie-Baxter state, ball up, roll off at a shallow tilt and sweep dirt away as they go, with a live cleanliness readout for each surface.
