摘要

本研究考察了疏水深度共晶溶剂（DESs）作为聚乳酸（PLA）薄膜增塑剂的性能，并将其与环氧大豆油（ESBO）和邻苯二甲酸二（2-乙基己基）酯（DEHP）等增塑剂的性能进行了比较。将dl -薄荷醇（氢键受体，HBA）与丙酮酸（Pyr）和乙酰丙酸（Lev）（氢键给体，HBD）混合制备DESs。DESs的密度与ESBO和DEHP相似，具有低粘度和剪切减薄行为。化学和热分析表明，通过较低的熔点和HBA与HBD之间的氢键相互作用，成功地生产了DESs。DESs增塑剂对PLA薄膜性能的影响取决于增塑剂的浓度。M-Pyr塑化膜在5 %浓度时吸水性和溶解度最低。DESs使PLA膜呈淡黄色，M-Lev显示更高的b* 值。随着增塑剂浓度的增加，透光率降低，紫外线阻隔性能增强。添加20 % M-Pyr和M-Lev可使DES增塑膜的拉伸强度提高21.73 ~ 80.60 %，断裂伸长率分别降低45.94 %和39.10 %。DESs对穿刺力、变形和热封能力也有影响。当增塑剂浓度为20% %时，des塑化PLA膜的水蒸气渗透率和氧渗透率分别降低了50% %和38.35% %。FT-IR分析证实了DESs与PLA的相容性，表明特征峰的变化可以忽略不计。DESs具有低挥发性、低迁移性和高抗氧化能力，是理想的增塑剂。薄荷醇为基础的疏水性DESs证明了PLA薄膜增塑剂的有效性，改善了机械和屏障性能，同时确保了稳定性和低挥发性。

Menthol and organic acid-based hydrophobic deep eutectic solvents as plasticizers in biodegradable poly (lactic acid) films

This study examined hydrophobic deep eutectic solvents (DESs) as plasticizers for poly (lactic acid) (PLA) films, comparing their performance to plasticizers like epoxidized soybean oil (ESBO) and di(2-ethylhexyl) phthalate (DEHP). DESs were produced by mixing DL-menthol (hydrogen bond acceptor, HBA) with pyruvic acid (Pyr) and levulinic acid (Lev) (hydrogen bond donors, HBD). The densities of DESs were similar to ESBO and DEHP and exhibited low viscosity and shear-thinning behavior. Chemical and thermal analysis revealed successful production of DESs, indicated by lower melting points and hydrogen bond interactions between HBA and HBD. PLA films plasticized with DESs showed varied properties depending on plasticizer concentration. M-Pyr plasticized films had the lowest water uptake and solubility at a 5 % concentration. DESs imparted a yellowish tint to PLA films, with M-Lev showing higher b* values. Light transmission decreased with increasing plasticizer concentration, enhancing UV barrier properties. Adding 20 % M-Pyr and M-Lev to DES plasticized films enhanced their tensile strength by 21.73–80.60 % while reducing elongation at break by 45.94 % and 39.10 %, respectively. DESs also influenced puncture force, deformation, and heat seal ability. Water vapor and oxygen permeabilities of DES-plasticized PLA films were reduced by 50 % and 38.35 % at 20 % plasticizer concentration. FT-IR analysis verified DESs' compatibility with PLA, indicating negligible shifts in characteristic peaks. DESs exhibited low volatility and migration with high antioxidant capacity, making them suitable plasticizers. Menthol-based hydrophobic DESs demonstrated effectiveness as plasticizers for PLA films, improving mechanical and barrier properties while ensuring stability and low volatility.

期刊介绍： Food packaging is crucial for preserving food integrity throughout the distribution chain. It safeguards against contamination by physical, chemical, and biological agents, ensuring the safety and quality of processed foods. The evolution of novel food packaging, including modified atmosphere and active packaging, has extended shelf life, enhancing convenience for consumers. Shelf life, the duration a perishable item remains suitable for sale, use, or consumption, is intricately linked with food packaging, emphasizing its role in maintaining product quality and safety.
