芳樟醇是各种天然精油的主要成分，广泛用于家庭、个人护理、食品和治疗配方。但是，由于其高挥发性和低稳定性，其应用受到限制。在本研究中，建立了一个有效的包封与高负载率连同热氧化还原双重响应和控制释放性能。采用碳碳双键对芳樟醇乳液进行改性，然后与热敏单体N-乙烯基己内酰胺进行沉淀聚合。制备的芳樟醇胶囊的平均尺寸和装载率为1.4 μ m和50.41wt%。芳樟醇胶囊具有热-氧化还原双重响应性和抗氧化-抗菌性能。特别是在模拟实际环境的刺激下，合成的胶囊表现出良好的抑菌效果。本研究为香精和精油的微胶囊化开辟了一条新的途径，扩大了香精和精油作为绿色生物抗菌剂的应用范围。
Linalool is a main component in different naturally derived essential oils, and widely used in household, personal care, food and therapeutic formulations. However, the application is limited due to its high volatility and low stability. In this study, an effective encapsulation with high loading ratio was built up together with thermal-redox dual responsiveness and controlled release properties. The emulsified linalool droplets were modified with carbon-carbon double bonds, followed by the precipitation polymerization with thermal sensitive monomer, N-vinyl caprolactam. The average size and the loading ratio of the prepared linalool capsules were 1.4 mu m and 50.41 wt%. The linalool capsules exhibited thermal-redox dual responsive properties and the antioxidant-antibacterial performance. Especially, responding to the stimuli mimicking practical circumstance, the synthesized capsules presented excellent bacteria inhibiting effect. This work may open a new path for fragrance and essential oil encapsulation, enlarging them as the green biological antibacterial agents in different applications.
