Developing　mechanically　strong　TPU-based　nanocomposites　with　integrated　fire　resistance,　smoke　suppression　and　electromagnetic　interference　(EMI)　shielding　performances　is　a　great　challenge.　Herein,　we　designed　a　mechanically　tough　and　fire　safe　thermoplastic　polyurethane/silicon　wrapped　ammonium　polyphosphate　polyphosphazene　functionalized　titanium　carbide/carbon　fiber　fabric　(TPU/SiAPZ@M/CF)　nanocomposite　with　good　EMI　shielding　properties.　The　as-prepared　TPU/SiAPZ@M　nanocomposites　showed　excellent　fire　safety.　For　example,　the　peak　of　heat　release　rate,　total　heat　release　and　total　smoke　release　of　TPU/SiAPZ@M-4.0　were　significantly　decreased　by　77.9　%,　46.7　%　and　51.6　%,　respectively,　compared　to　those　of　pure　TPU.　Additionally,　the　tensile　strength　of　TPU/SiAPZ@M-4.0/CF　reached　55.1　MPa.　Furthermore,　this　composite　demonstrated　acceptable　EMI　shielding　performance,　with　an　EMI　shielding　effectiveness　of　27.4　dB,　surpassing　the　commercial　demand　of　20　dB.　Therefore,　the　combination　of　superior　fire　safety,　high　mechanical　strength　and　excellent　EMI　shielding　performances　makes　the　hierarchical　TPU/SiAPZ@M/CF　nanocomposites　promising　applications　in　various　fields.　©　2023　Elsevier　Ltd
