Abstract To investigate the mechanical and thermal insulation properties of polydopamine/graphene oxide/polyurethane foam(PDA/GO/PUF), a novel process was employed to fabricate PDA/GO/PUF. The physical and mechanical properties of PDA/GO/PUF were tested using compression experiments and contact angle measurements, while the thermal insulation properties were characterized using an infrared thermal imager and combustion experiments. Microscopic mechanisms were explained via thermogravimetric(TG) analysis, scanning electron microscopy(SEM), and Fourier-transform infrared spectroscopy(FTIR). Results showed that the PDA/GO/PUF composite material subjected to cyclic load did not undergo permanent deformation and had a low energy loss coefficient, high maximum stress, and stable compression strength and Young's modulus, demonstrating excellent mechanical stability and fatigue resistance. The hydrophobicity of the PDA/GO/PUF surface was significantly improved compared to PUF, with a 13. 83° increase in contact angle. PDA/GO/PUF exhibited superior and more stable thermal insulation than PUF, without any dripping during combustion. The PDA nanocoating, self-polymerized on the GO/PUF foam surface, possessed outstanding adhesiveness, which also adsorbed GO particles detached from the GO/PUF onto the PDA/GO/PUF surface. During combustion, a dense carbon layer formed on PDA/GO/PUF, effectively insulating heat and slowing down the thermal decomposition rate of PDA/GO/PUF. Compared to PUF, its T_-50% decomposition temperature increased by 240 ℃, and the char yield increased by 21.65%, significantly enhancing the material's thermal stability. Characteristic peaks at 1 420 cm^-1and 1 714 cm^-1 belonging to the PDA coating's N-H bending vibration and the GO's C=O stretching vibration, respectively, further confirmed the successful fabrication of PDA/GO/PUF.
