Traditional　superhydrophobic　coatings　prepared　from　non-degradable　materials　tend　to　do　harm　to　the　environment　throughout　the　fabrication　process　as　well　as　after　being　discarded.　Great　efforts　have　been　devoted　to　exploring　more　environmentally　friendly　approaches　and　materials　to　settle　this　problem.　Here　we　report　an　eco-friendly　strategy　based　on　aqueous　systems　to　construct　superhydrophobic　coatings　on　various　fabrics.　Fabrics　were　first　coated　with　polydopamine　(PDA)　and　then　modified　with　the　stearic　acid　emulsion　to　introduce　the　desired　surface　morphology　and　energy.　The　as-prepared　fabrics　achieved　robust　superhydrophobicity　with　a　contact　angle　(CA)　about　162.0　degrees　and　sliding　angle　(SA)　about　7.8　degrees.　Moreover,　due　to　the　UV-absorbing　and　the　photo-thermal　conversion　ability　of　PDA,　the　modified　fabrics　exhibited　excellent　UV　shielding　and　solar-induced　self-healing　properties.　The　as-prepared　fabrics　also　possessed　high　efficiency　oil-water　separation　properties.　Without　the　usage　of　harmful　organic　solvents　and　the　addition　of　micro/nano-particles,　this　biodegradable　superhydrophobic　fabric　exhibited　a　clear　advantage　of　being　environmentally　friendly　over　conventional　coatings.　Furthermore,　the　facile　and　low-cost　fabrication　process　makes　its　large-scale　production　easy.
