Impact of Reactive Compatibilizers on the Properties of Poly(lactic acid)/Bamboo Flour Composites

The preparation of biodegradable wood plastic composites using polylactic acid (PLA) as the matrix and plant flours as the reinforcing phase aligns with the principles of sustainable development. However, there is a large polarity difference and poor compatibility between PLA and plant flours. To improve the performance of PLA/bamboo flour (BF) composites and simplify the process, this study modified PLA using glycidyl methacrylate (GMA), methacrylic acid (MAA), and maleic anhydride (MAH) as reactive compatibilizers. Composites were prepared from the modified PLA and BF using the hot-pressing method. The results indicated that all three reactive compatibilizers increased the polarity and surface free energy of PLA. GMA, MAA, and MAH were successfully grafted onto the PLA molecular chain, resulting in the formation of PLA-g-GMA, PLAg-MAA, and PLA-g-MAH graft copolymers. In addition, the interfacial compatibility between PLA-g-GMA and BF was the best, and the PLA-gGMA/BF composite had the lowest 24 h water absorption (2.17%). Furthermore, the PLA-g-GMA/BF composite showed the highest bending, tensile and impact strengths of 33.3 MPa, 14.7 MPa, and 1.33 kJ/m2, respectively, which were 63.8%, 104.9% and 4.7% higher than those of untreated PLA/BF composites, respectively. © 2025, North Carolina State University.

Transfer hydrogenation(TH) with in situ generated hydrogen donor is of great importance in reduction reactions, and an alternative strategy to traditional hydrogenation processes involving pressurized molecular hydrogen. Ammonia borane(NH3BH3, AB) is a promising material of hydrogen storage, and it has attracted much attention in reductive organic transformations owing to its high activity, good atom economy, nontoxicity, sustainability, and ease of transport and storage. This review focuses on summarizing the recent progress of AB-mediated TH reactions of diverse substrates including nitro compounds, nitriles, imines, alkenes, alkynes, carbonyl compounds(ketones and aldehydes), carbon dioxide,and N-and O-heterocycles. Syntheses protocols(metal-containing and metal-free), the effect of reaction parameters, product distribution, and variation of reactivity are surveyed, and the mechanism of each reaction involving the action mode of AB as well as structure-activity relationships is discussed in detail. Finally, perspectives are presented to highlight the challenges and opportunities for AB-enabled TH reactions of unsaturated compounds.

Effects of Ultrasonic Degradation on Physicochemical and Antioxidant Properties of Gleditsia Sinensis Seed Polysaccharides

作者： Yao, Qiuping Pu, Longlin Dong, Boyu Zhu, Dequan Wu, Wenwen Yang, Qiong Schoolof Chinese Ethnic Medicine Guizhou Minzu University Guizhou Guiyang50025 China Key Laboratory of the Development and Utilization of Guizhou Minority Medical Resources Guizhou Minzu University State Ethnic Affairs Commission Guizhou Guiyang50025 China

In this study, two degraded polysaccharides from Gleditsia sinensis seed were obtained under ultrasonic power treatments of 300 and 450 W. The physicochemical properties, structural characteristics, and antioxidant activities of the degraded and undegraded polysaccharides were studied and compared. LC and methylation analysis showed that the polysaccharides had similar basic structural features and were composed of the same monosaccharide units before and after degradation, but the ultrasonic treatment increased the total monosaccharide content and changed the Mannose/Galactose value. Furthermore, with the increase in the ultrasonic power, the molecular weight and intrinsic viscosity of polysaccharides decreased, and the micromorphology became looser. The scavenging capacities for 1,1-diphenyl-2-picrylhydrazyl and hydroxyl free radicals and the reducing ability were significantly increased by the ultrasonic treatment. In conclusion, ultrasonic treatment may be an effective way to improve the antioxidant activities of polysaccharides from G. sinensis seed, and further studies on its antioxidant mechanism are still needed. © 2024, The Authors.
