Here, we report a dual-emissive fluorescent sensing material that exhibits superior sensitivity and selectivity, enabling the efficient visual detection of different contaminants in aqueous systems. First, a mixed powder Metal–Organic Framework (MOF) probe with green and red luminescent emission properties was fabricated by modulating the doping ratios of Tb³⁺ and Eu³⁺ with the organic ligand 2,6-pyridine dicarboxylic acid (DPA). Subsequently, Eu/Tb-MOF was loaded onto the TEMPO-oxidized nanocellulose fiber (TOCNF) matrix via a simple physical mixing method, and the resultant composite film displayed a distinct visual fluorescent response to ciprofloxacin (CIP), norfloxacin (NOR) and ofloxacin (OFX) under irradiation with a 254 nm ultraviolet lamp. The results demonstrated that the Eu/Tb-DPA suspension with a molar ratio of Eu³⁺ :Tb³⁺ = 3:1 presented a favorable selective response to quinolone antibiotics including NOR, OFX and CIP, which not only allows the highly sensitive detection of quinolone antibiotics but also enables the discrimination of antibiotics of different categories based on their unique fluorescent signal patterns. The development of such dual-emissive fluorescent sensing materials can provide a solid theoretical foundation for the optimization of sensor design and further promote the practical application of relevant technologies in real-world environmental monitoring.</p></div>","PeriodicalId":658,"journal":{"name":"Journal of Polymer Research","volume":"33 10","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149132335","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}

However, previous studies on pyrene-based CMPs have mainly focused on donor-acceptor molecular design, functional-group modification, and heteroatom incorporation, while the effects of linker types and linking positions on the structure-performance relationship remain largely unexplored. Herein, we designed and synthesized a series of HER-active pyrene-based CMPs by varying the linker types and linking positions. Among the investigated catalysts, the phenyle-linked Py-BP exhibited the highest HER activity, achieving a hydrogen evolution rate of 2.80 mmol g^-1 h^-1 under UV-Vis irradiation with triethylamine (TEA) as the sacrificial hole scavenger, which can be further increased to 7.63 mmol g^-1 h^-1 after introducing 3 wt% Pt as a cocatalyst. In the ethynylbenzene-derived CMPs of Py-BZs, the para-linked Py-BZ1 exhibited lower photoluminescence emission, a stronger photocurrent response, and higher HER activity than the meta-linked Py-BZ2, suggesting more efficient charge transfer and suppressed electron-hole recombination. This work demonstrates that linkage, including linker types and linking positions, plays a pivotal role in regulating the photocatalytic HER activity of pyrene-based CMPs, providing valuable insights into the rational molecular design of CMP photocatalysts.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":658,"journal":{"name":"Journal of Polymer Research","volume":"33 10","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149132074","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}

The work investigates how differences in reaction rates between peroxide-based crosslinking and azo-type gas generation influence cellular structure and the resulting material properties. Three peroxide curing systems, dicumyl peroxide (DCP), 2,4-dichlorobenzoyl peroxide (PD), and di(4-methylbenzoyl) peroxide (PM), were systematically evaluated along with an azo-type blowing agent, with emphasis on their decomposition characteristics. The results demonstrate that the balance between curing and gas evolution plays a critical role in determining foam morphology, density, and mechanical performance. DCP-based systems produced compact structures with lower porosity, leading to improved strength and compression resistance, whereas PD-based formulations promoted greater expansion through better synchronization of curing and blowing reactions, yielding lighter materials. Furthermore, combining different curing agents generated a synergistic effect, enhancing both mechanical properties and expansion behaviour beyond those achieved with individual systems. The present work lies in using an intrinsic decomposition-rate mismatch between the peroxide curing agent and the azo-type blowing agent as the primary design parameter for making a silicone sponge, and in establishing dual-curing-agent synergy as an effective route to overcome the strength to expansion trade-off in silicone sponges. An optimum formulation containing 2 phr curing agent and 6 phr blowing agent provided a balanced combination of strength, flexibility, and thermal insulation. The DCP/PD-50 system exhibited superior overall performance compared with PD-50 alone, improving tensile strength from 0.52 to 1.37 MPa, elongation-at-break from 141 to 171%, and compression set from 85.2 to 15.6%, while maintaining similar hardness and specific gravity. SEM analysis confirmed the influence of vulcanizing agents on cell morphology and uniformity. Overall, this study is an effective strategy for developing advanced silicone sponge for sealing, insulation, and demanding industrial applications.</p></div>","PeriodicalId":658,"journal":{"name":"Journal of Polymer Research","volume":"33 10","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149133320","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}

Thermal analysis showed improved stability after grafting, with the apparent initial degradation temperature increasing from 245 °C for PVA to a maximum of 292 °C for 20% grafting (G20), followed by a slight decrease to 282 °C for G25. The activation energy at α = 0.5 followed the same trend, reaching its highest value for G20. Optical analysis revealed continuous band-gap narrowing from 5.54 eV for PVA to 4.91 eV for G25, while the Urbach energy increased from 0.42 to 0.64 eV, confirming increased localized-state density and structural disorder.

The dispersion behavior, chemical composition and morphology of TCE powder were characterized prior to incorporation into PBAT at 5–20 wt%. The effects of TCE powder loading on the chemical structure, thermal properties, morphology, mechanical properties and nicotine-release behavior of the PBAT composites were evaluated. Morphological analysis showed microspherical TCE powder. Dynamic light scattering revealed smaller hydrodynamic particle sizes of TCE powder dispersed in water, whereas its larger aggregates were observed in alcohol-based media. Preliminary agar-well diffusion method indicated changes in the growth pattern of <i>Aspergillus</i> sp. exposed to TCE solutions, although distinct inhibition zones were not observed. DSC analysis showed that TCE powder reduced PBAT crystallinity, while TGA indicated that the main thermal degradation behavior of the PBAT matrix remained largely preserved. Among the tested formulations, the composite containing 5 wt% TCE powder exhibited the the most favorable balance of tensile strength, stiffness and ductility, whereas higher TCE powder loadings reduced ductility and were associated with increased particle agglomeration and interfacial defects. Release studies demonstrated predominantly diffusion-governed nicotine release from the PBAT matrix, with quasi- or pseudo-Fickian behavior at lower TCE powder loadings and anomalous transport at the highest loading. The absolute amount of released nicotine increased with increasing TCE powder loading, although the fractional release relative to the theoretical nicotine content was formulation-dependent. A preliminary cradle-to-gate carbon footprint assessment indicated that incorporation of waste-derived TCE powder reduced the estimated carbon footprint by 13.30% compared with neat PBAT. These findings demonstrate the feasibility of incorporating tobacco-derived extract into biodegradable PBAT composites as a nicotine-releasing additive and support further investigation of their potential agricultural applications.</p></div>","PeriodicalId":658,"journal":{"name":"Journal of Polymer Research","volume":"33 10","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149035403","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}
