- •
Stainless steel master with different structural grating areas were ablated by picosecond laser.
- •
PDMS negative and positive replicas were prepared by imprinting for replicating hierarchical structures.
- •
Hierarchical structures on PDMS negative replica were conditionally copied from steel master.
- •
Replicas were sputtered on a gold film for exploring wettable effects of submicro/nano-structures.
- •
Submicro/nano-structures in hierarchical structures effectively enhanced the surface hydrophobicity.
