The　Ag　nanoparticles　were　formed　on　the　glass　by　DC　sputtering　and　high　temperature　annealing.　By　controlling　the　different　annealing　temperature　and　etching　time,　the　change　trend　transmittance　and　wettability　of　glass　were　studied.　The　size　and　distribution　of　Ag　nanoparticles　were　observed　by　scanning　electron　microscopy　(SEM).　The　change　of　the　transmittance　of　the　glass　after　etching　was　determined　by　the　UV-VIS　spectrophotometer.　The　surface　contact　angle　instrument　was　used　for　the　determination　of　changes　in　the　wettability　of　glass　surface　after　etching,　and　after　treatment　with　organic　fluorine　silane.　Results　show　that　when　the　annealing　temperature　reached　to　300　℃,　Ag　nanoparticles　were　more　uniform;　when　etching　time　was　4min,　transmittance　of　visible　light　can　be　increased　up　to　93.8%,　and　the　maximum　of　the　sample　is　3.8%　compared　with　the　original　sample;　the　hydrophilic　of　the　glass　is　more　obvious　after　etching,　the　contact　angle　measured　was　about　9°.　The　hydrophobicity　of　the　surface　of　the　glass　was　improved　after　chemical　modification,　but　the　enhancement　was　not　obvious,　and　the　contact　angle　of　the　surface　was　102°.　©　2015,　Beijing　University　of　Technology.　All　right　reserved.
