Durable　superhydrophobic　coating　was　fabricated　on　paper　substrate　by　solution-spraying　method　using　polydimethylsiloxane　(PDMS)　and　silicon　dioxide　nanospheres　(SiO2)　doped　poly(fluoreneyl　ether　ketone)　(PFEK).　The　effects　of　PDMS　dosage　and　SiO2　dosage　on　the　water　contact　angle　of　paper　were　investigated.　The　results　showed　that　when　both　PDMS　and　SiO2　dosage　were　2%　(based　on　the　mass　of　PFEK　and　N-methylpyrrolidone,　the　same　below),　the　water　contact　angle　of　the　coating　was　170°　and　the　sliding　angle　was　1°.　The　polymer　anchored　SiO2　on　the　surface　of　paper　fiber,　resulting　in　micro-nano　rough　structure　on　the　surface.　The　superhydrophobicity　was　caused　by　the　inhibition　of　droplet　infiltration　by　the　air　accumulated　under　the　hydrophobic　rough　surface.　The　prepared　PFEK/PDMS/SiO2　coated　paper　exhibited　excellent　superhydrophobicity　and　mechanical　stability　with　water　contact　angles　of　above　150°　after　40　cycles　of　wearing　tests　and　after　12　times　of　folding　tests.　Stretch　tests　revealed　that　the　PFEK/PDMS/SiO2　coating　enhanced　the　tensile　strength　of　ordinary　paper　from　10.1　MPa　to　37.8　MPa.　Moreover,　after　soaking　in　water　for　15　min,　the　tensile　strength　of　PFEK/PDMS/SiO2　coated　paper　was　25　MPa　and　still　had　better　mechanical　properties.　In　addition,　the　PFEK/PDMS/SiO2　could　resist　contamination　from　sticky　mud,　indicating　that　it　had　good　self-cleaning　performance.　©　2021,　Editorial　Office　of　FINE　CHEMICALS.　All　right　reserved.
