Developing flame-retardant epoxy resins (EPs) is essential to broaden their industrial applications, as inherent flammability restricts widespread use. In this study, commercial cerium oxide (CeO2) nanoparticles were modified with oleic acid and successfully assembled onto the surface of pyrophosphate piperazine (PAPP) through a simple solvophobic effect, constructing an integrated superstructure flame retardant, CeO2@PAPP, enhanced performance integration. Compared traditional blends, EP composite 10 wt% CeO2@PAPP displayed superior retardancy, thanks more subtle synergistic effects between retardant components favorable interface interactions. The achieved UL-94 V-0 rating increased limiting oxygen index (LOI) 34.2%. Significant reductions 56.3% in peak heat release rate (PHRR) 38.2% total (THR) observed. Furthermore, smoke (TSR), carbon monoxide yield (COPR), dioxide (CO2PR) decreased by 52.2%, 50.2%, 67.3%, respectively. Through comprehensive detailed characterization, it was discovered that can perform better both gas phase condensed phase, resulting properties. This study offers effective strategy for developing highly EPs, thereby expanding potential applications across various industries.

Abstract In this work, a tetra glycidyl eugenol cyclic siloxane resin (TGED 4 ) is synthesized, then further modified with 9,10‐dihydro‐9‐oxa‐10‐phosphaphenathrene‐10‐oxide (DOPO) to produce Si and P epoxy resins. After blending diglycidyl ether of bisphenol A (DGEBA) curing tannic acid (TA), high performance, fire‐retardant polymer networks are created. Near infrared spectroscopy (NIR) confirms the highly cured have low extractable content, while dynamic mechanical thermal analysis (DMTA) displays lower T g heterogeneous network increasing DOPO. The display maximum improvement in flexural modulus, strength, strain failure 20.6%, 55.5%, 78.8% respectively, at 65.4 MPa strength 2.8 GPa modulus comparable high‐performance networks. Thermogravimetric (TGA) shows that reduces stability, but contributes higher char yield despite Si. fire retardancy improve markedly measured via limiting oxygen index (LOI), from 26.5% 35.5%, V‐0 behavior readily achieved lowest DOPO content. Cone colorimetry peak heat release rate (PHHR) total (THHR) by 28% 42%. This work presents hybrid bio‐derived resins excellent good properties.
