摘要: A series of nanocomposites based on the biodegradable plastic, polylactide (PLA), have been prepared by melt-blending with graphene (Gra) and ionic liquid containing phosphonium ([PCMIM]PF6, IL) surface-functionalized (GIL). The morphology, mechanical properties, thermal stability burning behaviour composites were investigated Field Emission Scanning Electron Microscopy (FESEM), tensile test, impact Thermogravimetric Analysis (TGA), Limiting Oxygen Index (LOI), UL-94 test Cone Calorimeter Test (CCT), respectively. surface morphology chemical structure char residues explored FESEM Raman spectroscopy. It is confirmed that fire-retardant performance PLA/GIL was significantly improved compared to PLA/IL PLA/Gra; CCT data showed a reduction in heat release rate total released increase residue from TGA results. revealed catalytic charring effect liquid, physical isolating graphene, combined both (forming continuous compact layers) very efficient improving flame retarding properties nanocomposites.
