Abstract

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.
