Synergistic flame retardancy and smoke suppression in poly(lactic acid) using phytic-acid-modified alginate and ammonium polyphosphate
In this work, an alginate and calcium phytate-based complex (AlgCaPA) was synthesised and applied as a flame-retardant additive for poly(lactic acid) (PLA) in the presence of ammonium polyphosphate (APP) as a co-flame retardant. The total additive content was fixed at 15 mass%, and the ratio between AlgCaPA and APP w...
