This rubber is widely used in the automotive and other industries due to its performance and elasticity. However, synthetic rubber has largely replaced natural rubber in many applications because of the poor heat resistance of natural rubber. On the other hand, non-recyclable sulfur-based synthetic rubber composites pose a major environmental issue from the viewpoint of sustainability. In this report, a flexible (non-directional) crosslinking network based on ionic bonds in modified natural rubber (epoxy-modified NR) using dicarboxylic acid and dimethylimidazole (DMI) is presented, which eliminates the disadvantages of natural rubber and outperforms synthetic rubber without compromising its mechanical performance. Accelerated aging, temperature scanning stress relaxation, compression set, and temperature-dependent FT-IR analyses confirm the high thermal stability of ionically crosslinked natural elastomer. The ionic crosslinked rubber shows a significant improvement in initial degradation temperature (196 °C) compared to thermally stable synthetic elastomers, such as NBR (acrylonitrile butadiene rubber), CR (polychloroprene rubber), and peroxide-cured EPDM (ethylene propylene diene monomer). Unlike sulfur-cured elastomers, the ionically crosslinked natural rubber exhibits superior cut growth resistance and self-repairing capabilities, as demonstrated by X-ray microtomography. These findings, along with the natural origin of the developed crosslinked elastomers, can reduce environmental damage and the carbon footprint associated with sulfur-cured and petroleum-based synthetic rubber products.</div></div>","PeriodicalId":22097,"journal":{"name":"Sustainable Materials and Technologies","volume":"43 ","pages":"Article e01243"},"PeriodicalIF":8.6,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143137430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study optimized the dosage of reactants and investigated the effects of water background factors on the degradation efficiency of ibuprofen.

The effect of humic acid is related to its concentration in the solution. The degradation of ibuprofen is mainly attributed to the hydroxy radical ¹O₂. The efficient Cu(I)/Cu(II) redox cycle ensured the continuous production of these reactive oxygen species. The sulfur anions and pyridinic-N on the catalyst surface mediate the electron transfer during catalysis, accelerating the Cu(I)/Cu(II) cycle. At least 15 intermediate products were detected in the reaction residue, five of which were assessed to have higher toxicity to aquatic organisms than IBP.

Meanwhile, based on the process of preparing CNCs from commercial acid hydrolyzed wood, a systematic economic benefit comparison was conducted on the production of CNCs from SPR. The results showed that the degree of polymerization of the cellulose produced was 475.

A variety of characterization techniques were employed in this study, including XRD, nitrogen adsorption-desorption analysis, FESEM, FTIR, HRTEM, Zeta potential, Raman spectroscopy, contact angle measurements, DRS, Mott-Schottky analysis, and VSM.

The investigation of PZZF's photocatalytic activity against Rhodamine B highlights its enhanced efficiency, particularly under UV/H₂O₂ treatment, leading to complete degradation of the dye within 60 min. Several factors affecting the degradation process were explored, including pH, catalyst dosage, H₂O₂ concentration, and scavenger studies, providing comprehensive insight into the optimal conditions for maximum photocatalytic performance. The results from the radical trapping experiments demonstrated that hydroxyl radicals played a critical role in the degradation of Rhodamine B.
