Cassie's law
Cassie's law describes the effective contact angle θc for a liquid on a composite surface. The law explains how simply roughing up a surface increases the apparent surface angle. The law is stated as: where θ1 is the contact angle for component 1 with area fraction f1, and θ2 is the contact angle for component 2 with area fraction f2 present in the composite material. This equation takes on special meaning when in a 2-component system one component is air with a contact angle of 180°. With cosine(180) = −1, the equation reduces to:
