Although a great deal of experimental work is available in the literature on studies of static (equilibrium) contact angles, relatively little has been done on the dynamic aspects of the contact angle during spreading. Two distinctly different types of spreading are found: self spreading and force spreading. In both cases the contact angle changes with time, and is termed the dynamic contact angle. The impact, process of attachment, and subsequent spreading of drops of carbon tetrachloride at mercury/solution interfaces were recorded photographically. The effect of the history of the drop, prior to attachment at the interface, on the subsequent spreading phenomena is discussed. The reproducibility of dynamic contact angles is demonstrated. The effects of various factors such as gravity, temperature, and nature of the phases on the spreading process are considered. (88 refs.)
