| Abstract: |
| Spontaneous transportation of liquid on wetting pattern has promising applications in water-harvesting devices, heat transfer equipment, etc. However, the technology is limited due to the expensive and complex processing techniques, and weak transportation capacities. An arrow-shaped patterned surface based on a gradient hydrophobic substrate is proposed to address the problems of short transportation distance and slow speed, which can effectively improve liquid transportation performance. |
