A　simple　method　for　the　fabrication　of　increasing　the　hydrophobic　property　on　poly　(vinylidene　fluoride)　using　KrF　excimer　laser　irradiation　is　demonstrated.　The　results　showed　that　the　water　contact　angle　on　modified　area　was　increased　from　53　to　approximately　170　degrees.　It　was　found　that　the　change　in　wetting　behavior　correlated　with　the　formation　of　a　regular　wall-like　structure　and　the　appearance　of　C-CF(2)　and　C-F.　The　combined　effect　of　surface　morphology　and　surface　chemical　construction　induced　by　the　laser　irradiation　had　considerably　contributed　to　increase　the　hydrophobic　property　of　poly　(vinylidene　fluoride).　(C)　2010　American　Institute　of　Physics.　[doi:　10.1063/1.3452343]
