主　　题：flame retardancy flexible polyurethane foam graphene oxide silicone resin 

摘      要：A facile strategy was developed to fabricate flexible polyurethane(PU)foam composites with exceptional flame *** approach involves the incorporation of graphene oxide(GO)into a silicone resin(SiR)solution,which is then deposited onto a PU foam surface via the dip-coating technique and ***-transform infrared spectroscopy,scanning electron microscopy,and Raman spectroscopy measurements demonstrated that the SiR and GO were successfully coated onto the PU skeleton and the intrinsic porous structure of the PU foam remained *** effects of SiR and GO on the mechanical and thermal stability and flame retardancy of PU composites were evaluated through compression tests,thermogravimetric analysis,vertical combustion tests,and the limiting oxygen *** measurement results revealed that the composites(PU@SiR-GO)showed superior flame retardancy and thermal and mechanical stability compared to pristine PU or PU coated with SiR *** mechanical and thermal stability and the flame-retardant properties of the PU composites were enhanced significantly with increasing GO *** on the composition,microstructure,and surface morphology of PU@SiR-GO composites before and after combustion tests,a possible flame-retardance mechanism is *** work provides a simple and effective strategy for fabricating flame retardant composites with improved mechanical performance.
