The　laminated　carbon-nanotubes/Cu　(CNTs/Cu)　composites　were　fabricated　by　electrophoretic　deposition　(EPD),　spark　plasma　sintering　(SPS),　and　hot　rolling　to　achieve　a　good　combination　of　properties.　The　microstructure,　mechanical　properties,　and　electrical　conductivity　were　investigated,　and　the　strengthening　mechanism　was　discussed.　Results　indicated　that　functional　groups　were　introduced　onto　the　surface　of　CNTs　after　acid　treatment,　enabling　the　formation　of　an　optimal　CNT　deposition　morphology　on　the　Cu　matrix　at　an　electrophoretic　deposition　voltage　of　75　V.　The　sintered　CNTs/Cu　composite　exhibits　a　laminated　structure　with　coarse　grains　and　randomly　distributed　textures.　Compared　to　sintered　pure　Cu,　the　sintered　composite　demonstrates　a　42.07　%　increase　in　tensile　strength　and　a　17.8　%　improvement　in　elongation.　And　the　electrical　conductivity　reaches　93.05　%　of　the　International　Annealed　Copper　Standard　(IACS).　Subsequent　hot　rolling　refined　the　grains　and　reoriented　the　texture　to　deformation　textures.　The　hot-rolled　composites　achieve　a　tensile　strength　of　355　MPa,　an　elongation　of　12.2　%,　and　a　conductivity　of　85.53　%　IACS.　The　strengthening　mechanisms　of　CNTs/Cu　composites　involve　grain　refinement,　load　transfer,　and　thermal　mismatch　strengthening,　with　grain　refinement　as　the　primary　factor.　Grain　refinement,　crack　deflection,　and　bridging-pullout　of　CNTs　are　mainly　responsible　for　the　good　combination　of　strength,　ductility　and　electrical　conductivity.　©　2025
