Summary: A novel reactive flame retardant, PPDA, was synthesized by neutralizing PPOA with ODA. When incorporated into EP alongside DOPO, EP/PPDA/DOPO composite exhibited excellent flame retardancy and reduced heat release rate, smoke production, and total heat release. The presence of organic phosphorus structures and non-flammable nitrogen compounds contributed to its superior performance. PPDA/DOPO is a promising halogen-free alternative for flame retardants.

Summary: Fabricating a high-performing thermoset using bio-based flame retardant is critical for sustainable development. A novel flame retardant named DAL-x, fabricated by grafting DOPO onto lignin, is used to manufacture epoxy composites with industrial requirements. The resulting DAL-x/EP composite exhibits excellent flame retardancy and improved mechanical properties compared to pure EP. This work offers a feasible strategy for creating efficient bio-based flame retardants and preparing high-performance EP composites that meet fire retardancy requirements in industries.

Summary: By designing and preparing BMI monomers containing phosphate and phosphonate structure, the toughness and fire safety of BMI materials were improved. The incorporation of 5% BDTP and BDTDP significantly reduced the heat release rate and smoke production of BMI, achieving UL-94V-0 rating. Additionally, the impact strength of BMI was greatly increased. The study explored the effect of phenyl phosphate structure in BDTP and phenyl phosphonate structure in BDTDP on BMI performance.
