A　novel　polyvinylidene　fluoride　(PVDF)　membrane,　i.e.　Ag/TiO　2　/PVDF　composite　membrane,　was　prepared　via　the　blending/photo　reduction　combined　method　in　this　paper.　And　the　influence　of　Ag/TiO　2　embedment　on　the　surface　property　of　PVDF　membrane　was　discussed,　including　the　surface　hydrophilicity　and　visible-light　response　activity.　ATR/FTIR　characterization　certified　that　amount　of　hydroxyl　group　(OH)　was　formed　on　the　PVDF　membrane　surface　owing　to　the　embedment　of　Ag/TiO　2.　The　results　suggested　that　the　increased　hydrophilicity　of　PVDF　membrane　can　be　achieved　through　the　addition　of　Ag/TiO　2　nanoparticles　because　the　surface　hydroxyl　group　(OH)　had　great　contribution　to　membrane　hydrophilicity.　The　increased　hydrophilicity　was　also　demonstrated　by　the　contact　angle　measurement.　In　a　word,　Ag/TiO　2　improved　the　surface　hydrophilicity　of　PVDF　membrane　in　contrast　with　virgin　PVDF　membrane.　Besides,　Ag/TiO　2　nanoparticle　provided　PVDF　membrane　with　an　enhanced　visible-light　response　activity.　Ag/TiO　2　/PVDF　composite　membrane　showed　excellent　activity　on　degradation　of　methylene　blue　(MB)　and　inactivation　of　bacterial　under　visible-light　illumination.　I　hope　this　research　can　provide　a　new　way　for　PVDF　surface　modification.　©　2014　Elsevier　B.V.　All　rights　reserved.
