A　flower-like　super-hydrophobic　surface　on　the　copper　foil　was　fabricated　by　means　of　a　facile　method　using　solution　immersing.　The　water　contact　angle　of　this　surface　was　measured　to　be　as　high　as　156.2　degrees　after　modified　with　fluoroalkylsilane　(FAS)　coating.　To　study　its　effect　on　frost　deposition,　a　series　of　micro-observations　of　the　water　droplets　formation,　initial　frost　crystals　growth　and　frost　layer　melting　process　were　carried　out　on　both　the　super-hydrophobic　surface　and　the　plain　copper　foil　surface.　The　experimental　results　show　that　the　water　droplets　condensed　on　the　super-hydrophobic　were　smaller　and　present　a　more　spherical　shape　when　compared　with　that　on　the　plain　copper　foil　surface.　The　freezing　time　of　the　droplets　on　the　super-hydrophobic　surface　was　later　than　that　on　the　plain　copper　foil　surface.　Moreover,　the　super-hydrophobic　surface　can　restrain　initial　frost　crystals　formation　for　20　min　after　exposed　to　the　air　for　one　month.　The　mechanism　of　surface　hydrophobicity　influence　on　droplets　frozen　and　frost　formation　was　analyzed　theoretically　based　on　the　surface　wettability　and　the　phase　transition　theory.　(C)　2010　Elsevier　Masson　SAS.　All　rights　reserved.
