Solid-Like Slippery Coating with Highly Comprehensive Performance

Many 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.
