The study investigates the deformation of elastomeric surfaces under multiple compressive bending to modify the geometry

of micro-hyperbolic pillar arrays, enabling enhanced liquid repellency and tunable interlocking properties. During bending,

compressive stress transforms circular microholes into elliptical shapes. By repeating the process of compressive bending and

replication, we can achieve highly anisotropic pillar arrays for anisotropic wetting behavior with directional liquid mobility.

The bending process modulates pillar-to-pillar spacing along diff erent axes, further facilitating anisotropic liquid movement.

Furthermore, interlocking microarray patterns exhibit direction-dependent shear stress, resulting in a distinct mechanical

response. These fi ndings highlight a scalable, cost-eff ective strategy for designing smart surfaces with tailored wetting and

mechanical properties, with potential applications in droplet manipulation and specialized adhesives.
