Abstract

Bio-based flame retardants are rich in a variety of functional groups such as amino, carboxyl, hydroxyl, and unsaturated bonds. These functional groups enable the introduction of flame-retardant elements through multiple functionalization reactions. Bio-based flame retardants also exhibit good char-forming properties. They have garnered significant attention due to their high efficiency, low toxicity, environmental friendliness, and renewability. Depending on the source of the bio-based raw materials, bio-based flame retardants can be classified into bio-acid flame retardants, bio-phenol flame retardants, bio-aldehyde flame retardants, chitosan flame retardants, and lignin flame retardants. The article reviews the applications and synthesis methods of bio-based flame retardants in polymeric materials, discusses their flame-retardant properties, and provides an outlook on the limitations and future development of bio-based flame retardants. It points out that the future development of bio-based flame retardants should focus on improving performance, integrating multiple functions, reducing costs, enhancing synergistic effects, and promoting environmental friendliness.
