Slow　rebound　polyurethane　foam　(SPUF)　has　developed　rapidly　because　of　its　excellent　performance　in　sound　insulation,　energy　absorption,　and　tactile　sensation.　However,　the　friction-induced　electrostatic　charge　accumulation　occurs　easily　due　to　its　high　resistivity.　In　this　paper,　dimethyl　octadecyl　hydroxy　ethyl　ammonium　nitrate　(SN)　intercalated　reduced　graphene　oxide　(SN-RGO)　were　prepared　as　the　conductive　agent.　The　antistatic　slow　rebound　polyurethane　foam　(ASR-PUF)　was　prepared　with　SN-RGO/carbon　black　as　antistatic　system　and　silicone-modified　polyethylene　glycol　(Si-APEG)　as　low　temperature　resistant　agent.　The　structures　of　SN-RGO　were　investigated　by　Fourier　transform　infrared　spectra　(FT-IR),　wide-angle　X-ray　diffraction　(WAXD),　and　scanning　electron　microscope　(SEM),　respectively.　The　effects　SN-RGO　on　the　structures,　mechanical　properties,　low-temperature　resistance,　and　antistatic　property　of　ASR-PUF　were　studied.　It　was　found　that　SN-RGO　acts　as　heterogeneous　cell　nucleating　agent,　which　slightly　increases　the　apparent　core　density　and　slightly　decreases　the　porosity　of　ASR-PUF.　The　addition　of　SN-RGO　increases　both　the　tensile　strength　and　elongation　at　break　of　ASR-PUF,　and　has　little　effect　on　the　temperature　sensitive　index.　The　surface　resistance　of　ASR-PUF　decreases　to　1.1　×　108　Ω　with　a　SN-RGO　content　of　4　wt%,　thereby　achieving　an　antistatic　effect.　Highlights:　SN-RGO　acts　as　heterogeneous　cell　nucleating　agent　in　PU　foaming.　SN-RGO/carbon　black　provide　good　antistatic　property　and　mechanical　properties　without　affecting　the　low-temperature　resistance　of　ASR-PUF.　ASR-PUF　with　an　appropriate　content　of　SN-RGO　exhibits　excellent　comprehensive　performance.　©　2025　Society　of　Plastics　Engineers.
