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 μm 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.

高响应率的双重响应型芳樟醇胶囊具有出色的抗氧化和抗菌功效。
芳樟醇是不同天然衍生精油中的主要成分，并广泛用于家庭，个人护理，食品和治疗性制剂。但是，由于其高挥发性和低稳定性，其应用受到限制。在这项研究中，建立了具有高负载率的有效封装以及热氧化还原双重响应性和控释特性。用碳-碳双键修饰乳化的芳樟醇小滴，然后用热敏单体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负载比为1.4μm和50.41wt％。芳樟醇胶囊具有热-氧化还原双重响应特性和抗氧化-抗菌性能。特别，响应模拟实际情况的刺激，合成胶囊具有优异的抑菌作用。这项工作可能为芳香剂和香精油的包封开辟新的道路，使它们在不同的应用中成为绿色生物抗菌剂。
