Developing　highly　effective　flame　retardant　polymeric　materials　with　the　release　of　low　toxic　fumes　during　burning　still　keep　a　huge　challenge.　In　this　work,　we　demonstrated　successful　synthesis　of　titanium　carbide-reduced　graphene　oxide　(Ti3C2Tx-rGO)　hybrid　via　hydrogen　bonding　induced　assembly　of　Ti3C2Tx　and　rGO,　which　was　utilized　to　improve　the　thermal　and　fire　safe　performances　of　thermoplastic　polyurethane　elastomer　(TPU).　The　results　indicated　that　the　Ti3C2Tx-rGO　hybrid　showed　a　strong　adhesion　and　good　compatibility　with　TPU　host.　Furthermore,　as-prepared　Ti3C2Tx-rGO　hybrid　was　homogeneously　dispersed　in　the　TPU　matrix　due　to　the　mutual　intercalation　of　rGO　and　Ti3C2Tx　preventing　the　re-aggregation.　The　thermal　stability　of　TPU　was　dramatically　improved　after　the　introduction　of　Ti3C2Tx-rGO.　With　addition　of　2.0　wt%　Ti3C2Tx-rGO,　the　peak　of　smoke　production　rate　and　total　smoke　release　of　TPU　nanocomposite　were　remarkably　decreased　by　81.2%　and　54.0%,　respectively.　In　addition,　the　TPU/Ti3C2Tx-rGO-2.0　showed　distinct　reductions　in　the　peak　of　carbon　monoxide　production　rate　(54.1%)　and　total　carbon　monoxide　yield　(46.2%).　The　physical　barrier　effect,　the　catalytic　charring　of　Ti3C2Tx-rGO　hybrid　and　the　chemical　transformation　of　Ti3C2Tx　were　responsible　for　the　excellent　fire　resistance　of　TPU/Ti3C2Tx-rGO　systems.　This　work　provides　a　novel　strategy　to　significantly　reduce　the　fire　hazards　of　TPU,　thus　broadening　its　industrial　applications.　©　2020　Elsevier　Ltd
