Spin coating is one of the most used thin-film coating technique and for this reason, any new technique is typically compared to it.
A basic requirement of any coating is that it should form a uniform, defect-free surface. Surface and interfacial tensions play a key role in that.
Contact angle hysteresis is often measured with so-called tilting cradle or plate method. The measurement can be done either manually or automatically.
Most commonly used methods to study reservoir wettability are Amott-Harvey, USBM, and sessile drop contact angle.
