Summary: Three kinds of divalent metal ions (Ca2+, Cu2+, Zn2+) alginate/silver phosphate (MAlg/Ag3PO4) hybrid materials were prepared via an in-situ method and characterized by various techniques. The composites exhibited excellent flame-retardant properties and phosphorus-polymetallic flame-retardant effects. The flame retarding mechanism of MAlg/Ag3PO4 and the synergistic effect of Ag3PO4 and divalent metal ions were proposed based on experimental data from thermogravimetric analysis coupled with Fourier transform infrared analysis and pyrolysis-gas chromatography-mass spectrometry.

Summary: A series of metal polyhedral oligomeric silsesquioxane salts (POSS-M, M = Li or Na or K) were synthesized using click reaction and neutralization reaction. The chemical structure of POSS-M was confirmed by various analytical techniques. The introduction of POSS-M into epoxy resins resulted in epoxy composites with improved flame retardancy properties, as evidenced by UL-94 V1 rating and high limiting oxygen index (LOI) value. Additionally, the addition of POSS-M led to a significant reduction in peak heat release rate (pHRR) and the formation of compact char layers with sodium silicate on the surface, showcasing a novel flame retardant mechanism involving silicon-containing compounds.

Summary: In this study, poly(vinyl alcohol) composite aerogels (PVA/PCF/alpha-ZrP) with excellent flame retardancy were synthesized using exfoliated alpha-zirconium phosphate and phosphated cellulose through the multi-directional freezing method. The composite aerogel showed significantly reduced peak heat release rate, total smoke release, and CO production compared to pure PVA aerogel, while the limiting oxygen index value was improved. The flame retardancy mechanism involved crosslinking and carbonization of PVA chains promoted by PCF and alpha-ZrP, forming a barrier and reducing the emissions of combustible toxic gases.

Summary: A new phosphorus-nitrogen flame retardant APEHAP was synthesized and successfully grafted onto cotton fibers. The APEHAP-treated cotton fabric exhibited excellent flame retardancy and washing resistance without affecting its surface morphology and crystal structure. APEHAP also promoted thermal degradation and charring of the cotton fabric during combustion, effectively preventing flame spreading.
