Abstract Scope In more recent years there has been a significant push from industry leaders to develop sustainable flame retardants in order to avoid using halogenated products. A wide variety of alternatives have been studied, and among these is tannic acid, a polyphenolic biomacromolecule, but studying the flame retardancy of tannic acid in many media is difficult due to its solubility and chemical heterogeneity. One solution to solubilize tannic acid is to functionalize the end groups of tannic acid with polymer compatible molecules. However, the dispersability, mechanical properties, and flame retardancy of chemically modified tannic acid in epoxy have yet to be investigated. In this study, tannic acid was modified using acetic anhydride to enhance its dispersability in an epoxy medium. The dispersability of the modified and unmodified particles were investigated as well as the mechanical properties and the flame retardancy of the modified and unmodified composites.
