Control　of　wettability　is　of　significance　in　industry　as　well　as　our　daily　live.　Amorphous　carbon　(a-C)　films　with　nanostructured　surface　were　deposited　on　silicon　and　glass　substrates　at　different　substrate　temperatures　through　a　magnetron　sputtering　technique.　The　microstructures　of　the　a-C　films　were　studied　by　SEM　and　XPS,　which　indicate　that　the　surface　of　the　a-C　films　deposited　at　room　temperature　are　smooth　due　to　their　much　dense　sp(3)-bonded　carbon,　while　they　turn　to　be　more　porous　graphite-like　structure　with　elevated　deposition　temperature.　The　water　contact　angle　(CA)　measurements　show　that　these　pure　carbon　films　exhibit　different　wettability,　ranging　from　hydrophilicity　with　CA　less　than　40　degrees　to　super-hydrophobicity　with　CA　of　152　degrees,　which　reveal　that　the　surface　wettability　of　a-C　films　can　be　controlled　well　by　using　nanostructures　with　various　geometrical　and　carbon　state　features.　The　graphite-like　carbon　film　deposited　at　400　degrees　C　without　any　modification　exhibits　super-hydrophobic　properties,　due　to　the　combining　microstructures　of　spheres　with　nanostructures　of　protuberances　and　interstitials.　It　may　have　great　significance　on　the　study　of　wettability　and　relevant　applications.　(c)　2006　Elsevier　B.V.　All　rights　reserved.
