Abstract: The present disclosure provides a self-driven water collecting surface having a superhydrophilic-superhydrophobic structure, and a method for preparing the same, belonged to the technical field of water harvesting and superhydrophobic surfaces. The water collecting surface is a superhydrophobic surface with the distributed superhydrophilic region. The superhydrophilic region is a venation channel network structure consisting of hierarchical superhydrophilic channels. In the method, a pulsed laser is firstly adopted to form periodically distributed peak-pit microstructures and nanostructures, which is then modified with a low-surface-energy substance. Then, the low-surface-energy substance layer is removed by a pulsed laser again according to a venation channel network pattern. The laser scanned region is superhydrophilic, while the other regions are superhydrophobic. So that, the self-driven water collecting surface with the superhydrophobic-superhydrophilic structure is obtained.
