In this work, an environmentally friendly multicomponent flame retardant denoted as a sandwich-like 2D/2D montmorillonite/Zn2+-MEL-PA (MMT/ZnMPA) plate was successfully synthesized through "bottom-up" supramolecular self-assembly method, in which the ultrathin ZnMPA nanosheets were lying parallell on both sides of MMT plates. Then, MMT/ZnMPA served excellent performance nanofiller wood flour/polypropylene (WF/PP) composites. Microstructure characterization indicated that had uniform dispersion WF/PP composites with interfacial compatibility, thereby simultaneously improving mechanical properties and retardancy With incorporation 20 wt % plates, peak heat release rate total remarkably decreased by 28.1% 17.8% contrast to Moreover, tensile strength flexural increased 20.6% 15.2% compared composites, respectively. This work has presented facile tactic for integrating phosphorus nitrogen-containing plates develop high flame-retardant properties.

Biobased-functionalized metal–organic frameworks (Bio-FUN-MOFs) stand out from the crowd of candidates in flame-retardant field due to their multipathway mechanisms and green synthesis processes. However, exploring designing Bio-FUN-MOFs tend counteract problem compromising advantages MOFs themselves, which inevitably results a waste resources. Herein, strategy are ecologically regulated through acid–base balance is presented for controllable preparation by two birds with one stone, i.e., higher element loading retention more MOF structures. Specifically, buffer layer created on periphery ZIF-67 weak etching biobased alkali arginine resist excessive phytic acid when phosphorus source preserve integrity internal crystals as much possible. As proof concept, was almost completely etched absence arginine. The acid-functionalized yolk@shell structure (ZIF@Arg–Co–PA) obtained this strategy, flame retardant, reduces fire hazards polyurea composites. At only 5 wt % loading, ZIF@Arg–Co–PA imparted composites limiting oxygen index 23.2%, peaks heat release rate, total release, smoke production were reduced 43.8, 32.3, 34.3%, respectively, compared neat polyurea. Additionally, prepared have acceptable mechanical properties. This work will shed light advanced structural design polymer excellent safety, especially environmentally friendly efficient retardants.

Polyurethane foam (PUF) is the most widely used polymeric foam, owing to its low cost, minimal density, and superior thermal insulation characteristics. Nonetheless, applications are constrained by suboptimal acoustics fire performance coupled with safety concerns. This study introduces phosphorus-containing graphene oxide (D-GO)─a derivative of (GO)─that designed modified enhance PUF considerably. The D-GO composited (D-GO/PUF) was synthesized employing vacuum impregnation technology. Experimental results demonstrated that, compared pure PUF, peak heat release rate (pHRR) a maximum specific optical density smoke (Ds max) in trials pilot flames D-GO/PUF-3 were reduced up 55.34 45.18%, respectively. Furthermore, limiting oxygen index (LOI) 57.1% higher than that PUF.
