The　interface　properties　have　become　one　of　the　most　important　factors　that　affect　the　performance　of　widely-used　polymer　composites.　As　asimple　and　economical　method,　ultraviolet-ozone　(UVO)　can　stimulate　molecular　chains　upon　the　surface　of　polymer　matrix.　As　a　result,　the　modified　surface,　which　possesses　multiple　reaction　sites,　can　exhibit　distinct　properties　(such　as　surface　wettability　and　interface　bonding　performance　with　other　materials),　compared　with　the　bulk　material.　This　paper　summarizes　the　application　of　UVO-induced　polymer　surface　modification　(polyester,　polyolefin,　silicone,　rubber,　and　textile)　in　the　fields　of　electronics,　biological　treatment,　and　so　on.Then,　the　reaction　conditions　between　modified　polymer　surface　and　different　kinds　of　silane　coupling　agents　(methacryloxy,　epoxy,　amino,　and　mercapto)　are　reviewed.　At　last,　the　suggestions　for　the　possible　application　of　UVO　technology　in　the　future　are　given.　©　2022,　Editorial　Board　of　Material　Science　and　Technology.　All　right　reserved.
