The advancing contact angle is the angle formed at the solid-liquid interface when a liquid droplet is in the process of wetting a solid surface and is advancing over it. This angle represents the maximum wettability of the surface by the liquid, indicating how easily the liquid can spread on the solid. A larger advancing contact angle suggests that the liquid has more difficulty wetting the surface, which is essential in applications like coatings, adhesives, and inkjet printing.
congrats on reading the definition of Advancing Contact Angle. now let's actually learn it.
