Solid‐Like Slippery Coating with Highly Comprehensive Performance

Abstract

AbstractMany solar‐power and wind‐power devices in the world urgently demand self‐cleaning and de‐icing surfaces to ensure stable power generation. However, existing superhydrophobic surfaces and slippery liquid‐infused porous surfaces with self‐cleaning and de‐icing functions are difficult to apply due to various defects. Herein, a novel solid‐like slippery coating (SSC) is developed by constructing a smooth epoxy resin surface embedded with oil‐stored silica nanoparticles. The SSC has excellent water‐slippery capability to various water‐based liquids with low to super‐high viscosity, excellent durability and robustness, high hardness, strong adhesive strength to substrate, good optical transparency, and easy fabrication processes. This SSC also has remarkable non‐sticking, self‐cleaning, and de‐icing performances, showing promising practical applications in solar and wind power.
