To enhance the flame retardancy of polylactic acid (PLA), exploration bioderived retardants has captured focus researchers globally. Herein, a core–shell retardant is prepared through electrostatic self-assembly using ammonium polyphosphate (APP) as core and chitosan (CS)/tannic (TA) bilayer shell. In addition, Fe3+ ion introduced into outermost TA shell coordination with phenolic hydroxyl group, which can reduce droplets during combustion. The retardant, APP@CS@TA-nBL-Fe3+, structure (where "nBL" represents number coating layers CS bilayer) excellent for PLA. With 5 wt % PLA/5% APP@CS@TA-2BL-Fe3+ attains highest LOI value (31.6%) achieves UL-94 V-0 rating in vertical combustion tests light melt droplets. Furthermore, cone calorimetry results reveal that reduction 17.6% peak heat release rate 22.3% decrease total were achieved. Meanwhile, catalyzes matrix to form micro-cross-linked char layer blocking oxygen exchange. Moreover, not only 99.98% UV transmittance but also better mechanical properties after aging than neat This study presents convenient environmentally friendly approach preparing efficient biobased PLA, aiming broaden application

To endow epoxy resins (EPs) with outstanding flame-retardant and smoke-inhibiting effects, a multifunctional nanoparticle (SCP) has been designed prepared via simple approach, wherein Cu2O, melamine, phosphorus-containing flame retardants were successively deposited onto the surface of silica nanospheres. The incorporation low addition amount 2 wt % SCP within EP demonstrates significant improvement in retardancy. This enhancement is evidenced by notable increase limiting oxygen index to 29.2% attainment V-1 rating vertical burning test, contrast respective values 23.8% no for unmodified EP, respectively. Moreover, total smoke production, peak heat release rate, production rate CO EP/SCP-2 during cone calorimeter test decreased 10.2%, 26.1%, 37.0%, Besides, also endows composites commendable mechanical properties glass transition temperature (Tg), as 22.5% impact strength, an 8.1% rise tensile 9.5% Tg, comparing EP. mechanism analysis revealed that functions resin through both gas-phase condensed-phase mechanisms. Overall, proposed strategy presents promising approaches simultaneously enhancing fire safety performance polymer materials.

Waterborne polyurethane (WPU) has promising application prospects in paints and coatings owing to its low volatile organic compounds (VOCs), excellent abrasion resistance, mechanical properties. However, WPU is highly flammable, there a high demand for antibacterial properties practical applications. To date, effectively suppressing melt dripping remains challenge during combustion imparts property without compromising the inherent property. Herein, we report composites on basis of Cu(II)–phytate–aromatic Schiff base complex prepared from an aromatic derivative, copper(II) acetate, green renewable phytic acid. The resultant achieved limiting oxygen index (LOI) 27.5%. In UL-94 test, they achieve V-0 rating with no molten droplets self-extinguish within 1 s after first second flame Meanwhile, smoke emission inhibited cone calorimetry test. Moreover, exhibit killing rate 99.9% against Staphylococcus aureus Escherichia coli tensile toughness, providing useful reference designing fabricating flame-retardant composites.
