3D Microprinting of Super?Repellent Microstructures: Recent Developments, Challenges, and Opportunities

نویسندگان

چکیده

Liquid super-repellent surfaces, characterized by a low liquid–solid contact fraction, allow various liquids to bead up and freely roll off. Apart from liquid repellency, these surfaces feature several unique properties, including inter alia, self-cleaning, low-friction, anti-icing, anti-biofouling, making them valuable for vast array of applications involving liquids. Essential achieve such super-repellency is the bio-inspired reentrant or doubly micro-topography. However, despite their interfacial fabrication delicate 3D topographies conventional microfabrication methods extremely challenging. Recently, emerging microprinting technologies, particularly two-photon lithography, have brought new scope this field. With unparalleled design freedom flexibility, greatly facilitates design, testing, studying complex microstructures. Here, in microstructures are summarized, with focus on remarkable functionalities offered intricate topographies. Current challenges opportunities techniques further advance materials also discussed.
