摘要
The surfaces of ambient-temperature superhydrophilic tilting silicon nanowires (TSNWs) exhibit an anisotropic wetting performance at high temperature and a deposited drop moves directionally on this surface. A vapor film forming beneath the drop after spreading reduces the surface friction and the heat transfer efficiency between the drop and the surface, so the drop moves with a constant speed and little mass loss.
