Surface decoration of Halloysite nanotubes with POSS for fire-safe thermoplastic polyurethane nanocomposites

Wei Wu et al.

Summary: In this study, POSS containing amino group was covalently grafted on the surface of HNTs, leading to the uniform dispersion of modified HNTs in TPU matrix and significantly improved tensile properties and fire safety of TPU nanocomposites. The addition of HNTs-POSS effectively reduced heat release rate and smoke release, forming a continuous and compact char layer that hindered heat diffusion and evaporation of volatile gases, ultimately enhancing the fire safety of TPU nanocomposites.

Sulfonated Block Ionomers Enable Transparent, Fire-Resistant, Tough yet Strong Polycarbonate

Ting Sai et al.

Summary: Polycarbonate (PC) is widely used for high-end products due to its high transparency and balanced mechanical properties. However, existing fire retardants and toughening agents fail to meet the requirements of PC. By designing sulfonated ionomeric fire retardants, PC can achieve better fire retardancy and toughness.

Dopamine-modified poly(styrene) nanospheres as new high-speed adsorbents for copper-ions having enhanced smoke-toxicity-suppression and flame-retardancy

Ziyu Jin et al.

Summary: Polydopamine-coated polystyrene (PS@PDA) nanospheres exhibit excellent Cu2+ adsorption capacity, which can be further used to prepare PS nanocomposites with enhanced flame retardancy. A new evaluation system based on analytic hierarchy process is introduced for comprehensive analysis of fire safety of samples, showing that PS@PDA absorption of Cu2+ leads to reduced smoke and toxic gas production, improving overall fire safety performance.

Transparent, highly thermostable and flame retardant polycarbonate enabled by rod-like phosphorous-containing metal complex aggregates

Ting Sai et al.

Summary: By utilizing a one-step solvothermal method, new rod-like phosphorus-containing metal complex aggregates (CePn) were successfully synthesized as a flame retardant for polycarbonate, reducing peak heat release rate and total smoke release while maintaining UL-94 V-0 rating and a 27.3% limiting oxygen index. The final PC composite retains high transparency of 90.1% and comparable tensile strength, while significantly enhancing thermal stability.
