Ferulic acid, a phenolic compound found in various natural sources, exhibits strong antioxidant properties and the ability to enhance the mechanical strength and barrier properties of biopolymer films. The review covers its chemistry, sources, and methods for isolation, emphasizing its application in crosslinking various biopolymers, including polysaccharides such as starch, cellulose, chitosan, and pectin, as well as proteins like gelatin. The crosslinking process improves the properties of these biopolymers, making them suitable for sustainable packaging solutions. The study further discusses the integration of ferulic acid with biopolyesters to create films and coatings aimed at food preservation, providing an eco-friendly alternative to conventional plastic packaging. The use of ferulic acid in enhancing the shelf life and safety of packaged food products through its incorporation in biopolymer films is highlighted, showcasing the dual role of this compound in both film development and food preservation. This comprehensive review offers insights into the versatility and efficacy of ferulic acid-based crosslinked biopolymer films in advancing sustainable packaging technology, with a focus on practical applications for food safety and environmental sustainability.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144091604","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 matrix material was made in aqueous medium and characterized by various techniques. Higher swelling and drug release were observed at pH 7.4 than at pH 1.2. The drug loading efficiency of the nanocomposite was determined to be 39.1 mg g−1 for 5-FU and 42.8 mg g−1 for CUR. About 93.9% of 5-FU and 72.2% of CUR were released from the nanocomposite at pH 7.4 during 24 h. The drug release kinetics and mechanism were best fitted to the first-order kinetic and Higuchi square rootmodels, respectively. The release of 5-FU and CUR adhered to the Fickian and non-Fickian diffusion mechanism, respectively. The cell viability of the drug-loaded nanocomposite was above 85%, indicating cytocompatibility of the developed polymer matrix. The results highlight the potential of the prepared nanocomposite as a suitable DDDS for enhancing bioavailability of 5-FU and CUR in the gastrointestinal tract for cancer therapy.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144091606","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 resulting polymers exhibit number-average molecular weights (Mn) ranging from 36.6 to 91.8 kg mol−1, with polydispersity indices (Đ) between 1.7 and 4.8. The FeFe-DMCC catalyst demonstrated exceptional performance, achieving polymer yields of up to 1058 grams per gram of catalyst within a 12-h reaction period. A significant breakthrough in this work is the catalyst's ability to effectively suppress the oxygen-sulfur exchange reaction (O/S ER), a side reaction that typically generates mixed linkages. Instead, the process achieved outstanding selectivity, exceeding 99%, for monothiocarbonate units, with no formation of cyclic thiocarbonate byproducts. This remarkable control underscores the catalyst's efficiency in producing clean, well-defined polymers. Additionally, the copolymer composition, particularly the ratio of monothiocarbonate to ether units, can be finely tuned by varying the COS feed ratio, enabling precise customization of the polymer's properties. These findings establish FeFe-DMCC as a highly effective and selective catalyst for COS/PO copolymerization, offering a pathway to produce high-quality PPMTC with tailored characteristics and minimal byproduct formation. This work represents a significant advancement in sustainable materials development.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144091603","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 chemical structure of TPAEs is confirmed by Fourier transform infrared spectroscopy (FT-IR) and hydrogen magnetic resonance spectroscopy (1H-NMR). Differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA) results show that short-chain polyetheramine (Jeffamine-ED600) has good compatibility with PA66, which limits crystal growth and greatly reduced crystallinity, can be used as diluent to reduce the melting point of the material. However, the microphase separation of long-chain polyetheramine (Jeffamine-ED900) and PA66 leads to the increase of crystallinity, and the melting temperature does not decrease significantly with the increase of soft segment content. Mechanical properties tests show that all TPAEs exhibit good mechanical properties and excellent energy dissipation, with tensile strength up to 45 MPa and elongation at break up to 630%. The introduction of PEO unit results in the water absorption of TPAEs ranging from 25 to 65%, and the surface resistivity varying between 2.45 × 10⁹ and 1.6 × 10¹⁰ Ω, suggesting the synthesized TPAEs are suitable for use as permanent anti-static materials.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144091931","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}
