  1. ; (, Hilton Head Workshop 2024: A Solid-State Sensors, Actuators and Microsystems Workshop)
    This paper presents a novel idea to enable superhydrophobic (SHPo) surfaces with exceptional resistance to cutting while remaining soft and stretchable. For the first time, we achieve these unprecedented mechanical properties through strategic heterogeneous integration of a highly entangled polymeric substrate with a top layer of SU-8 micro-pillars. To realize resistance to cutting in soft materials, our innovation utilizes a polymer within which the entanglement outnumbered the crosslinks so that the cutting stress can be redistributed along the long polymer chains and to many other chains. We demonstrate the unique cut-resistant property of the highly entangled hydrogel, the integration of the hydrogel to fabricate SHPo surfaces, and water-repellency tests against cutting.
