However, their intrinsic hydrophobicity and limited reinforcement restrict broader use in coatings and electronic materials. In this study, poly(bis(4-trifluoromethylphenoxy)phosphazene) (PBTP) was synthesized via nucleophilic substitution of polydichlorophosphazene (PDCP), obtained by thermal ring-opening polymerization of hexachlorophosphazene. To enhance performance, mesoporous SiO₂ nanoparticles were surface-functionalized with N-phenyl-3-aminopropyltrimethoxysilane (NP-3-APTMS) to introduce hydrophobic phenyl groups and improve compatibility with the PBTP matrix. A series of novel PBTP/silica nanocomposites with silica loadings of 1–10 phr were prepared using a solution-casting method. Structural characterization by NMR (¹H, ¹³C, ³¹P) and FTIR confirmed successful polymer synthesis and substitution. BET analysis demonstrated successful surface functionalization of SiO₂ nanoparticles, evidenced by a significant reduction in surface area and pore volume after modification. SEM showed uniform nanoparticle dispersion at low loadings, while higher loadings led to agglomeration. Thermal analysis indicated improved stability, with T_5% increasing from 351.1 °C (neat PBTP) to 386.3 °C (PBTP–δ). Heat resistance index and char yield also increased with silica content. Flame-retardant testing confirmed UL-94 V-0 ratings and rising limiting oxygen index values up to 46.6%. Char analysis revealed dense phosphorus- and silica-rich layers, promoting synergistic gas- and condensed-phase flame retardancy. Water uptake and contact angle measurements indicated reduced moisture absorption and enhanced hydrophobicity, with contact angles increasing from 121.1° to 135.4°. These results demonstrate that surface-functionalized silica nanoparticles effectively reinforce PBTP, enhancing thermal stability, flame retardancy, and hydrophobicity. The nanocomposites are promising candidates for high-performance flame-resistant coatings and advanced electronic insulation materials.</div></div>","PeriodicalId":17276,"journal":{"name":"Journal of the Indian Chemical Society","volume":"103 3","pages":"Article 102476"},"PeriodicalIF":3.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146171896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we designed the orthogonal experiment to evaluate the effects of recycled fine aggregate (RFA) admixture, water-glass admixture and sand-cement ratio on the compressive strength, and chloride curing ability of SSRAC. The hydration products and microscopic morphology of SSRAC were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS). The results showed that the RFA was the main factor to affect the compressive strength, and chloride curing ability of SSRAC.
