The patent application describes an anti-icing coating designed to protect vehicle parts, like sensors and surfaces, from ice, dirt, and harsh conditions.
GM has submitted a patent application for an anti-icing coating designed for vehicle components and sensors. This innovative coating uses two materials that work in tandem to prevent ice buildup while keeping surfaces clean and functional.
The coating consists of two main components. The first, known as the continuous phase, is made from a unique fluorine-based material that resists water, oil, and dirt, helping to maintain a dry and clean surface. The second component, the discrete phase, is composed of a material that absorbs water, helping to prevent ice formation by managing water exposure. Together, these components form a strong and efficient coating.
What sets this coating apart is the way the two materials are combined. Instead of blending together, they remain separate as distinct layers that complement each other. These layers are chemically bonded using a crosslinking molecule, enhancing the coating's strength and longevity. This design ensures the coating can withstand tough conditions, such as exposure to oil, fuel, and extreme weather, without losing its effectiveness.
Unlike other coatings that only repel water, GM's coating actively prevents ice formation by incorporating a water-absorbing layer. It's also more durable, lasting longer under harsh conditions. This type of coating is especially useful for autonomous vehicles, which rely on a variety of sensors and systems that must function seamlessly without human intervention.
