Greetings
I am looking for papers that have quite good data pertaining to the advancing contact angle of the sessile drops of surfactant solutions. Any relevant journal articles, conference papers etc would be appreciated
Thank you in advance
If you are interested in the effect of the surfactant I suggest data from pendant drop or maximum pressure bubble Methode. Otherwise you also have to consider the effect of the solid (which you haven’t specified).
regards
Michael
PS the determination of advancing and receding angles is more challenging and often differently performed as generally assumed. (Compare to our publications in this field)
The contact angle of surfactant solutions on solid surfaces is depending on the surfactant adsorption at the three interfaces (LG, SL and SG with L=liquid, G=gas and S=solid) that are involved. The asurfactant adsorption behavior at the SL and SG interface strongly depend on the type of solid. A discussion on the surfactant adsorption and sessile drop contact angle can be found in

Hi, I am finishing mi PhD on wettability problems. I have studied advancing and receding contact angles both static and dynamic ones. I have consider the hysteresis effect but no change was done on the solid surface energy (adding surfactant to the coating).
You can find my research here: http://pabloravazzoli.com.ar/publications.html if no one of my publications is useful to you, probably some of the references in there will be.
Also you can search on 2004 ElSherbini work. He studied sessile drops on incline substrates with different combinations of liquid and solids.
