In　recent　years,　various　biomimetic　materials　capable　of　forming　gaseous　plastron　on　their　surfaces　have　been　fabricated　and　widely　used　in　various　disciplines　and　fields.　In　particular,　on　submerged　surfaces,　gaseous　plastron　has　been　widely　studied　for　antifouling　applications　due　to　its　ecological　and　economic　advantages.　Gaseous　plastron　can　be　formed　on　the　surfaces　of　various　natural　living　things,　including　plants,　insects,　and　animals.　Gaseous　plastron　has　shown　inherent　anti-biofouling　properties,　which　has　inspired　the　development　of　novel　theories　and　strategies　toward　resisting　biofouling　formation　on　different　surfaces.　In　this　review,　we　focused　on　the　research　progress　of　gaseous　plastron　and　its　antifouling　applications.
