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　droplet-jumping　events　were　observed　on　the　superhydrophobic　surfaces　under　different　relative　humidity　(RH).　Droplet-jumping　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,　anti-fouling　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.　©　2022　Elsevier　B.V.
