Claim 0:
1. A self-driven water collecting surface having a superhydrophilic-superhydrophobic structure, wherein the water collecting surface comprises a superhydrophilic region and a superhydrophobic region, and the superhydrophobic region is a superhydrophobic surface, the superhydrophilic region is a venation channel network structure comprising superhydrophilic channels of different orders connected to each other;
the superhydrophilic-superhydrophobic structure comprises:
periodically distributed peak-pit microstructures comprising alternately distributed micro-peaks and micro-pits, and
nanostructures distributed on the peak-pit microstructures;
wherein in the superhydrophobic surface, the superhydrophilic-superhydrophobic structure further comprises a superhydrophobic substance located on the peak-pit microstructures.
