摘要: Intumescent flame retardant poly(butylene succinate) (IFRPBS) composites with enhanced fire resistance were prepared using graphene as synergist. The morphology of fracture surfaces the was investigated by scanning electron microscopy (SEM). limiting oxygen index (LOI) values increased from 23.0 for pure PBS to 31.0 IFRPBS 20 wt % IFR loading. addition further improved LOI and exhibited excellent antidripping properties. UL-94 V0 materials obtained a formulation 18 2 graphene. MFI measurement indicated that presence significantly melt viscosity restrained dripping. thermal degradation gas products IFRPBS/graphene systems monitored thermogravimetric analysis (TGA), real time Fourier transform infrared spectrometry (RTFTIR), analysis-Fourier (TG-FTIR). X-ray photoelectron spectroscopy ...
