"never-wet surfaces struggle to maintain their properties when exposed to hot water/ steam, as heat often causes protective air layer to collapse... overcome using superhydrophobic multiscale hollow glass microspheric thermal insulation coating... low-cost, scalable, repels droplets as hot as 95°C, durable: lasts >80 hours/ withstands 1 million impacts... improves efficiency/ lifespan of: steam power plants, water desalination facilities, and electronic cooling systems"
