Abstract

We designed 12-amino acid peptides as antifreeze protein (AFP) mimetics and tuned the antifreeze activity of the peptides by their structures. Moreover, these short peptides were first immobilized to surfaces as an anti-icing coating. We discovered that the peptides with higher antifreeze activity exhibited better anti-icing performance. It is the first time that short peptides were successfully applied to fabricate anti-icing surfaces, which is certainly advantageous in comparison to the AFP anti-icing coatings previously reported.
