In　this　study,　we　fabricated　a　sprayable　polyester-SiO2　anti-condensation　coating.　The　coating　exhibited　superhydrophobicity　and　condensation　resistance　at　various　sub-cooled　temperatures.　We　found　that　the　number　of　nucleation　sites　is　greatly　related　to　surface　energy　and　dynamic　growth　of　droplets.　Besides,　different　dropletjumping　events　were　observed　on　the　superhydrophobic　surfaces　under　different　relative　humidity　(RH).　Dropletjumping　events　of　50　times　were　observed　under　48%　RH　in　an　11-min　cooling　period,　which　is　five-times　higher　than　those　under　other　relative　humidity　conditions.　To　avoid　contamination　triggered　nucleation　events,　antifouling　property,　a　key　factor　of　an　anti-condensation　surface,　was　also　studied.　Oil　repellence　and　contamination　tests　verified　the　good　anti-fouling　property　of　our　coating.　The　resistance　of　our　coating　to　scratches　has　been　investigated　by　nano-indentation,　cross-cut　adhesion,　and　sandpaper　abrasion　tests.　Compared　with　other　reported　anti-condensation　coatings,　our　coating　proved　to　be　better　than　previously　reported　anti-condensation　coatings.　Our　work　opens　significant　research　and　market　opportunities　for　the　widely　used　polyester　coatings　in　anti-condensation　applications.
