Method And Apparatus For Dynamic Wetting Angle Measurement
US Patent:
4275587, Jun 30, 1981
Filed:
Oct 1, 1979
Appl. No.:
6/081089
Inventors:
Edgar B. Gutoff - Brookline MA
Assignee:
Polaroid Corporation - Cambridge MA
International Classification:
G01N 1302
US Classification:
73 644
Abstract:
A method of measuring the dynamic wetting angle between a liquid and a solid surface moving into the liquid as a function of the speed of the solid surface relative to the liquid comprising the steps of moving the solid surface into the liquid at a constant speed, adjusting the angle of the surface entering the liquid until the wetting angle is equal to the angle between the solid surface and the quiescent surface of the surrounding liquid, and measuring said adjusted angle. In another embodiment, the speed of the solid surface entering at a selected angle is adjusted until the meniscus adjacent the surface becomes level, and the speed is measured.
