AB - Of the theoretical models reviewed the kinetic analysis of Lopez, Miller and Ruckstein would appear to offer a satisfactory model for the spreading of perfluropolyether lubricants and silicones. The spreading of drops in the 'gravity-viscous' regime was monitored and the results are in reasonable agreement with theoretical predictions. Spreading gradients of 0.097-0.2 were measured compared to a theoretical slope of 0.125. The slope was also found to be invariant with drop volume, but not with fluid viscosity. The second result is contrary to prediction, and may result from an intermolecular force contribution to spreading. Support for the theory that drops can experience successive regimes of spreading is provided by the observation that the spreading gradient of some low viscosity fluids increase as spreading proceeeds. The formation of a ridge near the spreading edge was also observed. This was considered to be due to the predominance of intermolecular forces. Tests on an experimental fluid show that minor modifications in composition can lead to a great increase of spreading rates. (from paper)
