Abstract

Material scientists have investigated biodegradable materials with excellent mechanical properties and high melting points. In this study, an AB-type poly(butanediol sebacate-butane diol terephthalate)-polylactic acid (PBSeT-PLA) macromolecule was synthesized using the esterification-polycondensation-esterification method, with hexamethylene diisocyanate (HDI) unit serving as a chain extender. Analysis using FTIR, ¹H NMR, and XRD confirmed the synthesis of PBSeT-PLA rather than a mere blend. Differential scanning calorimetry (DSC), thermogravimetric analysis (TG), and Vicat softening temperature (VST) tests revealed that the melting and Vicat softening points of PBSeT-PLA were increased by 30 °C and 15 °C, respectively, compared to PBSeT. Furthermore, the tensile strength, puncture load, and tearing strength of P2 (PBSeT-PLA, with an NCO to OH ratio of 1.5) were enhanced by 32.8%, 38.5%, and 71.8%, respectively, compared to PBSeT. Enzymatic degradation experiments demonstrated that the synthesized materials are biodegradable, with degradation initiating at the material surface. Overall, the thermal and mechanical property improvements suggest that PBSeT-PLA holds promise for applications in agricultural films and packaging materials.

通过合成 AB 型 PBSeT-PLA 大分子提高 PBSeT 共聚聚酯的机械和热性能

材料科学家研究了具有优异机械性能和高熔点的可生物降解材料。本研究以六亚甲基二异氰酸酯（HDI）单元为扩链剂，采用酯化-缩聚-酯化法制备了ab型聚己二酸丁二醇-对苯二甲酸丁二醇-聚乳酸（PBSeT-PLA）大分子。利用FTIR， 1H NMR和XRD分析证实了PBSeT-PLA的合成，而不是单纯的共混物。差示扫描量热法（DSC）、热重分析（TG）和维卡软化温度（VST）测试表明，与PBSeT相比，PBSeT- pla的熔融点和维卡软化点分别提高了30°C和15°C。与PBSeT相比，NCO / OH比为1.5的PBSeT- pla的抗拉强度、穿刺载荷和撕裂强度分别提高了32.8%、38.5%和71.8%。酶降解实验表明，合成的材料是可生物降解的，降解始于材料表面。总的来说，热性能和机械性能的改进表明，PBSeT-PLA在农用薄膜和包装材料中的应用前景广阔。

期刊介绍： Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field. The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest. Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials. Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
