Bioinspired in situ repeatable self-recovery of superhydrophobicity by self-reconstructing the hierarchical surface structure

Inspired by the biological self-recovery mechanism of superhydrophobicity, a new class of waxgel material with sustainable hierarchical surface micro-structures has been reported. After being damaged or removed, the waxgel material can self-reconstruct its surface layer both chemically and structurally, as well as successfully recovers its superhydrophobicity. In addition, it shows non-fluorinated composition, durability to severe mechanical challenges, and self-recoverable surface structures without external input of any kind such as; heat, UV, plasma etc., which distinguishes waxgel from any previous self-healing superhydrophobic systems. This strategy will open a new path for improving the long-term functionality of different interfacial materials.

Automated summary

Inspired by the biological self-recovery mechanism of superhydrophobicity, a new class of waxgel material has been reported, which features sustainable hierarchical surface micro-structures and the ability to self-reconstruct its surface layer after damage or removal. This material does not require external input for self-recovery and exhibits durability and non-fluorinated composition.
