Healable antifouling films are fabricated by the exponential layer‐by‐layer assembly of PEGylated branched poly(ethylenimine) and hyaluronic acid followed by post‐crosslinking. The antifouling function originates from the grafted PEG and the extremely soft nature of the films. The rapid and multiple healing of damaged antifouling functions caused by cuts and scratches can be readily achieved by immersing the films in normal saline solution.
