摘要/Abstract

摘要： 针对芳樟醇易挥发、热稳定性差、无法自支撑等缺点限制了工程化应用效能的问题,提出纤维微胶囊一体结构的等级制包络稳态化策略。通过设计以聚酰胺-胺型树枝状大分子(PAMAM)为“分子微胶囊”支架,高效包络芳樟醇分子,利用分子动力学模拟验证PAMAM和芳樟醇的包络机制并研究最佳负载率(负载率为60.3%),将包覆芳樟醇的PAMAM与玉米醇溶蛋白共混纺丝形成等级制双包络结构的长效抗菌芳香微纳米非织造材料。结果表明:双包络稳态化策略可有效使得微纳米非织造材料对芳樟醇的负载率从2.61%提升到13.9%,其热稳定性提高15.38%;力学性能方面,其断裂强力为21.23 cN,断裂伸长率为6.25%,较包络前分别提高了90.52%和53.56%,抑菌圈提升为10.2 mm。

Abstract:

Objective Linalool, a primary constituent of lavender essential oil, is renowned for its versatile properties, including anti-inflammatory and anti-bacterial effects, as well as its sedative and hypnotic qualities. Additionally, it exhibits potent anti-oxidation capabilities. Owing to these beneficial attributes, linalool is extensively utilized in various health-related fields, such as sleep aids, antibacterial products, and anxiety relief. Its natural calming effects make it a valuable component in aromatherapy and other wellness practices.Despite these advantages, linalool's inherent volatility and poor thermal stability present significant challenges that can limit its application efficiency and effectiveness. Its tendency to evaporate quickly can lead to a loss of potency, while its instability at higher temperatures can affect its shelf life and reliability in various formulations. In order to overcome these drawbacks and harness linalool's full potential, a novel hierarchical envelope stabilization strategy for fiber microcapsules is introduced.

Method A sophisticated hierarchical envelope stabilization strategy for fiber microcapsules is presented, which is a groundbreaking approach in the field of encapsulation technology.Micro-nano composite nonwowens were developed, which was meticulously crafted using the electrospinning technique. Polyamide-amine dendrimers (carefully designed organic molecules known for their high branching and functionality) were chose as the main material for building molecular microcapsules. Through electrospinning technology, zein-coated molecular microcapsules are prepared to achieve the sustained release of linalool.

Results The inclusion mechanism of polyamide-amine dendrimers and linalool was verified by molecular dynamics simulation, and the optimal loading rate (64.9% for polyamide-amine dendrimers) was investigated.Besides, the long-active antibacterial aromatic micro-nano nowowens (the loading rate of linalool increased from 2.61% to 13.9%) was formed, and the mechanical properties (breaking strength 21.23 cN, elongation at break 6.25%) were improved by 90.52% and 53.56%, respectively.

Conclusion The micro-nano scaffolds developed through the electrospinning of zein and polyamide-amine dendrimers have significantly improved the storage stability of linalool when kept at room temperature.Encapsulating linalool within the fibrous matrices of the micro-nano nonwowen not only protected the compound from degradation but also prolonged its antibacterial efficacy over an extended period. This advancement in encapsulation technology has allowed linalool to retain its potent antibacterial activity, making it a viable candidate for a wide range of application in the field of medical dressing, the sustained release of linalool from these micro-nano scaffolds can provide a continuous antimicrobial effect, reducing the risk of infection in wound healing environments. Furthermore, in food packaging, the integration of linalool-containing microcapsules into packaging materials can serve as a natural preservative, prolonging the shelf life of perishable goods by inhibiting the growth of bacteria and fungi.

Key words: aromatic and antibacterial, functional nonwowen, electrospun micro-nano material, linalool, polyamide-amine dendrimer
