Antistatic　nylon-6　(PA6)　composites　have　attracted　considerable　attention　due　to　their　tailored　properties　for　electronics,　textiles,　and　automotive　applications.　In　this　paper,　the　antistatic　PA6　composites　comprising　with　polypropylene　(PP),　aminated　multi-walled　carbon　nanotubes　(MWCNTs-NH2)　and　aminated　carbon　black　(CB–NH2)　were　prepared　by　melt　blending　and　compression　molding.　In　the　composite　system,　PP　was　used　as　the　co-matrix　to　assist　the　phase　separation　of　PA6.　MWCNTs-NH2　and　CB-NH2　were　introduced　as　conductive　fillers.　All　composites　showed　good　thermal　stability　with　the　T5　%　higher　than　376　°C　and　the　composites　containing　fillers　showed　higher　residues　after　thermal　degradation　due　to　the　good　thermal　stability　of　MWCNTs-NH2　and　CB-NH2.　The　DSC　and　XRD　results　indicated　that　the　crystallization　properties　of　the　composite　materials　were　determined　by　PA6　and　PP　rather　the　conductive　fillers.　In　general,　the　introduction　of　conductive　fillers　decreased　the　mechanical　properties　but　effectively　improved　the　conductivity　of　the　composites　and　then　the　antistatic　properties.　Besides,　the　antistatic　analysis　and　mechanical　test　denoted　that　MWCNTs-NH2　and　CB-NH2　showed　synergistic　effect　on　improving　the　antistatic　and　mechanical　properties　of　the　composites,　which　was　more　evident　at　high　MWCNTs-NH2　quantity.　The　micromorphologies　obtained　by　SEM　first　confirmed　the　ductile　fracture　of　these　composites,　and　then　disclosed　a　two-phase　structure　of　PA6　and　PP　polymer　matrix,　where　the　conductive　fillers　were　found　in　the　PA6　phase.　Considering　both　mechanical　and　antistatic　properties,　the　composite　(PCNB-3)　containing　both　3　phr　MWCNTs-NH2　and　CB-NH2　was　proposed　for　the　antistatic　PA6　composite.　©　2025
