Fabrication of UV-Triggered Liquid-Repellent Coatings with Long-Term Self-Repairing Performance

The
biomimetic fabrication of Nepenthes as a new class of liquid-repellent
surface materials has attracted much attention recently, but there
still remains big challenges, for example, short-serving life, instability,
and so forth. Herein, we develop a novel strategy to fabricate robust
slippery liquid-repellent coating by the synthesis and use of silicon
oil-contained ultraviolet-responsive microcapsules. Owing to the physical
and chemical inertness of silicon oil and the substantial randomly
dispersed microcapsules in the coating, this nepenthes-like liquid-repellent
coating can not only endure different harsh environments but also
have excellent long-term self-healing functions.
