Dynamic Contatc angle? Evaluate the rougnhess trhow hysteresis? Is qualitative but if you compare samples...
Surface Profilometers are the main devices that can be used to measure surface roughness. There are two types of surface profilometers, stylus type (Talysurf, Dektak etc.) and optical type (Zygo, VEECO etc.). The stylus type is normally used to measure 2D or large step surface profiles (roughness), and the optical type can be used to measure 3D and small step surface profiles. AFM can also be used to measure surface profile, when high resolutions are required (up to tens of nanometers in x and y and up to sub-nanometer in z). However, AFM is only practical for measuring the surface profile of a local very small area.
Yes I know what you are talking about, but I want to ask if someone has experience in the correlation between roughness and contact angle measurments with liquids.. Thank you
Sara, I think it will be better if you raise a new question in order for others to answer it.
