However, its intrinsic flammability, characterized by a low limiting oxygen index (LOI) of 17.4% and rapid melt-dripping behavior during combustion, poses severe fire hazards, hindering its application in aerospace, electrical insulation, public infrastructure, and some areas with high fire prevention requirements. To address this limitation, the development of flame-retardant PE composites has emerged as a pivotal research frontier. This paper first introduces the combustion process and reaction mechanisms of PE materials. It then reviews the application of flame retardants in PE and their effects on the flame retardancy of these materials. The advantages, limitations, and synergistic effects of these additives are discussed, alongside future directions for sustainable flame-retardant technologies. The flame retardants discussed include phosphorus-based flame retardants, inorganic flame retardants, expanding flame retardants, and biomass-based flame retardants.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 41","pages":"19593 - 19614"},"PeriodicalIF":3.9,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145316487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A series of glasses with varying CeO₂ concentrations (0.6–15 wt.%) were synthesized via the melt-quenching technique in alumina crucibles, yielding homogeneous, amorphous materials characterized by SEM, EDX, XRD, FTIR, Raman spectroscopy, and differential thermal analysis (DTA). Potentiometric titration confirmed the presence of tetravalent cerium (Ce⁴⁺) and trivalent cerium (Ce³⁺) as the dominant oxidation state. Structural studies revealed Ce-induced silicate network depolymerization, evidenced by shifts in Qⁿ unit distribution (Q⁴ → Q³/Q²) in FTIR/Raman spectra and increasing O:Si ratios. Despite this depolymerization, the effective cationic field strength (ECFS) rose with both Ce³⁺ and Ce⁴⁺ incorporation, driven by their high bond strengths, counteracting network fragmentation. Consequently, the glass transition temperature (T_g) increased monotonically with Ce⁴⁺ content (611 °C to 634 °C), while thermal stability (S) decreased due to enhanced crystallization tendencies. Aluminum oxide diffusion from crucibles (1–3 at%) further complicated compositional trends, influencing ECFS and crystallization kinetics. Optical basicity (Λ≈0.58) remained invariant, underscoring its insensitivity to localized Ce⁴⁺ structural changes. These findings highlight valuable insights into the structural role of cerium in soda–lime glasses and its potential for optimizing glass properties for advanced technological applications.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 40","pages":"18774 - 18788"},"PeriodicalIF":3.9,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10853-025-11568-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145256722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chitosan, a natural polymer with hemostatic properties, is among these materials. Sponges of chitosan (CS) and poly(ε-caprolactone) (PCL) were prepared by emulsion–solvent displacement for possible uses as a topical hemostatic agent. Chitosan solutions and PCL emulsions were prepared, respectively, in water containing 1% acetic acid and 2.5 wt.% PCL in acetone/Tween^® 80 (surfactant), and then mixed in proportions of 100:0; 75:25; 50:50; 25:75; 0:100, followed by freeze-drying to produce CS/PCL sponges. Samples were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and Fourier-transform infrared spectroscopy (FTIR). Hemagglutination assay, absorbance and hemolysis tests were also carried out to study the interactions between sponges and blood tissue. It was observed that CS favored CS/PCL sponge formation while sponges were not produced when only PCL was used. Moreover, SEM images demonstrate that CS/PCL sponges have an interconnected porous morphology. XRD patterns showed that the individual morphologies of CS and PCL were maintained, which indicates a low interaction between the components in the mixture as can also be corroborated by FTIR, since there were no significant changes in the characteristic frequencies of functional groups in the sponges when compared to the spectra of pure polymers. Results also showed that sponges with up to 50% CS had a good hemagglutination capacity, demonstrating the potential of these blends as hemostatic materials for surgical purposes such as in dental surgeries.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 40","pages":"19087 - 19098"},"PeriodicalIF":3.9,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145256776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that within the low sputtering power range, as the sputtering power of the HfO₂ target increases, the surface density and hardness of the coating are improved, while the friction coefficient and wear loss are significantly reduced. The main mechanism is as follows: The increase in HfO₂ content promotes the amorphous transformation of the WS₂ matrix, and the dispersedly distributed HfO₂ particles can passivate the contact interface between the steel ball and the coating, achieving a low friction coefficient by inhibiting adhesive wear. However, within the high sputtering power range, as the power continues to increase, although the coating hardness keeps rising, the friction coefficient and wear loss increase significantly. This phenomenon stems from the coating oxidation caused by the formation of W–O bonds induced by excessive HfO₂, ultimately leading to the degradation of tribological properties. When the sputtering power is 80 W, the lubricating phase of amorphous WS₂ and the hard phase of HfO₂ reach the optimal synergistic balance, and the tribological properties of the coating are the best at this point (with an average friction coefficient of 0.062 and a wear rate of 1.571 × 10⁻⁸ mm³ N⁻¹ m⁻¹).
