To improve the flame retardancy and smoke suppression effect of epoxy resin (EP), a new organic–inorganic hybrid (MH@ZB‐ODOPB) was fabricated. First, hierarchical‐structured particles (MH@ZB) were prepared by gradually depositing zinc borate (ZB) on the surface of magnesium hydroxide (MH) via a heterogeneous deposition process. Second, MH@ZB was modified with 10‐(2,5‐dihydroxyphenyl)‐10‐hydro‐9‐oxa‐10‐phospha‐phenanthrene‐10‐oxide (ODOPB) to obtain MH@ZB‐ODOPB. Finally, the chemical structure and form of MH@ZB‐ODOPB were analyzed via X‐ray diffraction, Fourier transform infrared spectroscopy, X‐ray photoelectron spectroscopy, and scanning electron microscopy. The characterization results show that ZB was loaded onto the surface of MH, and ODOPB was grafted on the surface of MH@ZB. The cone calorimetry test results show that when 7.5 wt% MH@ZB‐ODOPB was added into EP, the peak heat release rates, total heat release, total smoke production, and peak smoke production rates decreased by 51.8%, 42.4%, 58.1%, and 66.1%, respectively. Moreover, EP/MH@ZB‐ODOPB exhibited a limiting oxygen index of 33%. These results show that the incorporation of MH@ZB‐ODOPB into EP composites considerably improved the flame retardancy and smoke suppression properties of EP composites. The double action of MH@ZB‐ODOPB in condensed and gas phases was investigated by analyzing the carbon residue and pyrolysis gas. Furthermore, the implementation of ODOPB improves the mechanical properties of EP composites.

“…But the plastic sector also has some unavoidable drawbacks, like environmental pollution, 2 over‐exploitation of oil resources 3 and so on. Therefore, the recycling of waste materials 4–6 and the creation of bio‐based materials 7 are progressively emerging as trends that are essential for the materials industry's future growth.…”

A novel bio‐based carbon forming agent (Mg@PA‐CS) containing P and N elements was were synthesized using the complexation characteristics of chitosan (CS) and phytate (PA). The flame retardant behavior of poly(lactic acid) (PLA)/Mg@PA‐CS/APP composites (addition of 20 wt% of different ratios of Mg@PA‐CS and APP to polylactic acid composites) were investigated by the limiting oxygen index (LOI), vertical burning test (UL‐94), cone calorimetry test (CCT), and thermogravimetric analysis (TGA). Due to the biphasic flame retardant and synergistic effect, since the 20 wt% flame retardant system (Mg@PA‐CS:APP = 1:2), PLA composites passed the UL‐94 test V‐0 rating, reached 34% LOI value. The peak heat release rate (PHRR) and total heat release rate (THR) were reduced to 1/2 of the pure PLA, char residue could be as high as 11.49% at 800°C. Moreover, the flame‐retardant mechanism of PLA composites during thermal decomposition was analyzed using a scanning electron microscope (SEM) and the coupling techniques of TGA linked with FT‐IR (TG‐FTIR).
