The　thermal　and　chemical　stabilities　are　two　key　factors　limiting　the　commercial　application　of　superhydrophobic　coatings.　Herein,　a　thermally　and　chemically　stable　fluorinated　poly(aryl　ether)　(FPAE)　was　used　for　the　first　time　to　construct　superhydrophobic　coatings　by　a　facile　solution　spraying　process.　Distinct　nanosheet　structures　were　formed　for　the　FPAE,　which　after　the　incorporation　of　SiO2　and　carbon　nanotube　(CNT)　turned　into　a　hydrangea-like　structure　with　high　roughness　and　low　surface　energy.　As　a　result,　superhydrophobic　coatings　were　obtained　with　the　water　contact　angle　(WCA)　reaching　about　170°　and　the　rolling　off　angle　(RA)　reaching　less　than　1°.　The　superhydrophobicity　was　maintained　after　a　variety　of　rigorous　tests,　including　high-temperature　baking,　acidic　and　alkaline　solution　immersions,　ultrasonic　treatments,　friction　evaluations,　etc.　The　self-cleaning,　anti-corrosion,　and　oil–water　separation　capabilities　of　the　FPAE/SiO2/CNT　coating　were　successfully　demonstrated.　Therefore,　the　FPAE　is　a　promising　resin　for　the　preparation　of　low-cost　and　high-performance　superhydrophobic　coatings.　Graphic　abstract:　[Figure　not　available:　see　fulltext.]　©　2021,　The　Author(s),　under　exclusive　licence　to　The　Materials　Research　Society.
