A phase-field model: Contact angle hysteresis driven by multistable surface composition

Puntos clave

• Contact angle hysteresis arises due to the multistable nature of surface compositions, affecting fluid interactions with surfaces.
• The phase-field model reveals that changes in surface composition can lead to significant variations in contact angles, impacting fluid behavior.
• This analysis provides a foundational understanding of the interplay between surface properties and liquid interfaces.
• These findings may aid in the design of materials that optimize wettability for specific applications, enhancing performance.
