Superior　flame　retardancy　and　excellent　smoke　suppression　are　two　significant　issues　in　thermoplastics,　espe-cially　for　thermoplastic　polyurethane　(TPU)　with　extensive　application　in　industrial　fields.　It　is　of　great　signif-icance,　but　hardly　achievable,　to　simultaneously　impart　these　properties　to　TPU.　Herein,　we　reported　the　titanium　carbide　and　coupling　agent　functionalized　the　silicon-wrapped　ammonium　polyphosphate　(NSiAPP@Ti3C2Tx)　via　hydrogen-bonding　interaction　and　microencapsulation,　which　were　then　adopted　to　enhance　the　fire　safety　of　TPU.　The　as-prepared　TPU/9.0NSiAPP@1.0Ti3C2Tx　composite　showed　the　V-0　rating　in　the　UL-94　testing　and　its　LOI　value　was　increased　to　27.6%.　Besides,　the　cone　calorimetry　results　indicated　that　the　peak　of　heat　release　rate,　total　smoke　release,　total　carbon　monoxide　yield　and　total　carbon　dioxide　yield　of　the　TPU/9.0NSiAPP@1.0Ti3C2Tx　were　significantly　decreased　by　78.1%,　72.6%,　53.7%　and　67.5%,　respectively,　as　compared　to　those　of　pure　TPU.　The　outstanding　charring　effect　and　excellent　barrier　function　together　with　the　prominent　terminating　action　of　the　NSiAPP@Ti3C2Tx　hybrid　caused　the　remarkable　enhancement　of　the　fire　resistance　for　TPU　composites.　This　work　offers　a　promising　strategy　for　endowing　TPU　composite　with　high　flame　retardancy　and　superior　smoke　suppression.
