Biologically Inspired Materials Exhibiting Repeatable Regeneration with Self-Sealing Capabilities without External Stimuli or Catalysts

A new insect‐cuticle‐ and fruit‐browning‐mimetic film exhibiting simultaneous self‐healing and self‐sealing properties only by ambient oxygen without external stimuli is developed. The film is formed at the liquid/air interface via crosslinking of phenolic compounds and poly(amine) chains. The film...

Description
Summary:A new insect‐cuticle‐ and fruit‐browning‐mimetic film exhibiting simultaneous self‐healing and self‐sealing properties only by ambient oxygen without external stimuli is developed. The film is formed at the liquid/air interface via crosslinking of phenolic compounds and poly(amine) chains. The film can be self‐healed over a hundred times under ambient air at room temperature without exogenous materials and stimuli.
