Abstract Scope Springtails (Collembola) are wingless arthropods which rely on epidermal respiration. They developed unique surface patterns which can prevent them from suffocation in temporarily flooded or organic-contaminated habitats. The mushroom-like, overhanging structures on springtail exoskeleton can effectively repel not only water but even low-surface-tension organic liquids. In thermodynamics, an upward suspension force generating from surface tension pins the liquid on top of the structure and leads to Cassie-Baxter state rather than Wenzel state. In this study, superomniphobic surface inspired by springtails was fabricated by advanced additive manufacturing techniques. Micro-structural features were characterized by SEM and wettability was evaluated by static contact angle, hysteresis, sliding angle, break-in pressure and underwater properties measurements. Results show that oil and organic liquids can be repelled by the springtail-inspired, synthetic patterns without surface modification. Such bio-inspired design and optimization can further lead to liquid-repellent and anti-adhesive applications.
