| Abstract: | In the present study, a biomass-derived metal-phenolic networks (MPN) were used as charring agent and flame-retardant synergist for Ethylene-vinyl acetate/Ammonium polyphosphate (EVA/APP) composites. Compared with the polyphenol, the thermal stability of MPN was improved remarkably, making it a good match for EVA. Meanwhile, Limit oxygen index test revealed that MPN endowed EVA/APP composites with enhanced flame-retardant performance. The reason on improvement in the flame retardancy of composites was also discussed and the corresponding mechanism was proposed. © 2018 Wiley Periodicals, Inc. J. Appl. Polym.
