Continuous ethanol release at ice–solid interfaces keeps ice at bay for nearly two years
Interfacial ethanol layers from liquid-packed coatings maintain long-lasting and super-low ice adhesion at temperatures as low as -60°C
Scientists have made a polymer system that slowly releases ethanol to create a non-freezing lubricating layer at ice–material interfaces. The system can last for 593 days at extremely low temperatures without having to replenish the ethanol.
