Glycerol contact angle

WebJun 17, 2024 · The literature also indicates that this contact angle is dependent on the amount of glycerol added to the film composition. Generally, the more glycerol, the lower the wetting angle and the better the water distribution on the film surface. These studies were performed for the contents of 33 and 50% glycerol (Basiak et al. 2024). WebMar 15, 1989 · For miscible liquids, the decay of the interface is, in general, so rapid that it practically excludes measurement of interfacial tension. However, if one liquid is present in the form of a gel, and if the other liquid is placed as a drop upon the gel, there is often enough time to measure contact angles.
