Journal of Colloid and Interface Science（SCI, IF:4.233）Summary:
The dynamic contact angle was confirmed velocity-independent with 10 -9 < Ca <10 -5 (contact line velocity V 02 =0.13565490 μm/s) and it can be described by a two-angle model with desirable accuracy. A modified two-angle model was developed and an empirical form was obtained from experiments. For different liquids contacting the same surface, the advancing angle θ adv θ adv mathContainer Loading Mathjax approximately equals the static contact angle θ o θ o mathContainer Loading Mathjax . The receding angle θ rec θ rec mathContainer Loading Mathjax was found to be a linear function of θ adv θ adv mathContainer Loading Mathjax , in good agreement with our and other experiments from the literature.Co-author:
