(a) Previous methods for deducing mechanism and (b) our proposed novel approach for revealing the real burning behavior and flame-retardant mechanism. Figure 2. (a) Illustration of the previous structure–activity relationship theory and (b) our proposed theoretical flame retardancy model based on the flame-retardant roles. Figure 3. AI-assistant self-iterative, high-throughput, and generalizable flame-retardant material design framework. Traditional flame retardants and flame-retardant polymeric materials struggle to meet the stringent requirements of emerging areas. For instance, fire incidents involving new energy vehicles, extreme wildfires, and hydrogen fuel cells, etc. present extreme conditions with higher temperatures and greater heat flux, demanding enhanced thermal stability and heat shock resistance in flame-retardant polymeric materials. Additionally, materials used in ultrahigh-voltage electrical systems must withstand extreme voltages and large currents, necessitating improved electrical insulation and thermal stability to ensure operational safety and reliability. Some halogen-based and certain phosphorus-based flame retardants are still associated with persistent, bioaccumulative, and toxic (PBT) hazards. (25−27) Future research should prioritize the development of low-toxicity, low-pollution flame-retardant solutions that minimize environmental accumulation risks while preventing the release of hazardous gases or persistent pollutants during combustion. Traditional flame retardants are primarily derived from nonrenewable fossil resources, which conflicts with carbon neutrality and sustainability goals. Future research should explore the use of renewable biomass resources, such as polysaccharides, lignin, and proteins, to develop efficient and low-carbon flame retardants. Flame retardants are typically incorporated into polymeric materials through physical or chemical means, where incorporating flame-retardant elements often complicates waste management by limiting material reuse and increasing environmental impact. (28) Therefore, considering the recyclability of flame-retardant polymeric materials in the initial material design or the physical/chemical/biological recovery of the discarded flame-retardant polymeric materials is necessary to reduce the impact on the environment and improve resource utilization.
