Abstract
The spreading dynamics of water droplets on hat silicon surfaces is investi gated. It is shown that, for situations close to complete wetting, the radi us evolution with time can be described using a power law with a nonstandar d exponent of in. This dynamics is interpreted using a hydrodynamic model w ith an invariant dissipation profile. Such a description is also consistent with the slow dynamics observed for larger contact angles.
