Interest　in　advanced　multifunctional　composite　materials　has　generated　extensive　discussions　on　materials　endowed　with　high　fire-resistance,　mechanical　strength,　and　excellent　electromagnetic　interference　(EMI)　shielding.　We　designed　a　feasible　and　low-cost　method　for　preparing　mechanically　robust　thermoplastic　polyurethane/triazine-rich　polyphosphazene　functionalized　titanium　carbide@copper　phytate/carbon　fiber　fabric　(TPU/PZM@CP/CF)　nanocomposites　with　enhanced　fire　retardancy　and　EMI　shielding　performances.　The　as-prepared　TPU/PZM@CP-2.0/CF　demonstrated　excellent　mechanical　toughness,　with　a　tensile　strength　of　57.8　MPa.　Additionally,　this　nanocomposite　exhibited　superior　EMI　shielding　performances,　with　an　EMI　shielding　effectiveness　of　29.7　dB　and　a　normal　shielding　effectiveness　of　24.8　dB/mm,　surpassing　that　of　most　other　TPU-based　nanocomposites.　Furthermore,　the　thermal　stability　and　fire　resistance　of　the　TPU/PZM@CP　nanocomposites　were　significantly　improved.　For　instance,　the　peak　of　heat　release　rate　and　the　peak　of　smoke　production　rate　of　the　TPU/PZM@CP-2.0　respectively　decreased　by　41.5%　and　21.5%,　compared　to　those　of　neat　TPU.　In　this　work,　the　simple　preparation　method　and　outstanding　comprehensive　performances　of　the　mechanically　strong　multifunctional　TPU/PZM@CP/CF　have　tremendous　potential　for　applications　in　defense,　smart　electronic　device　and　aerospace.　©　2023　Elsevier　Ltd
