Bio-derived tannic acid-Eu( iii ) coordination synergizes with aluminum diethylphosphinate for low-loading and high-efficiency flame retardancy in PA66
Abstract
with an increased fire performance index (FPI). Thermal analysis in air showed that the composite formed a stable carbonized layer at elevated temperatures, and the coordinated polyphenolic network favored a more compact char structure. Gas phase analysis further indicated that the system released fewer combustible volatiles during decomposition. The material retained about 97.6% of the tensile strength and about 87.8% of the impact strength of the neat sample, reflecting a largely preserved mechanical response. Because tannic acid has long been used in biological macromolecule modification and biointerfaces, the Eu@TA approach provides a bio-derived option that can be extended to polymer systems requiring both fire resistance and compatibility with biopolymer components.
