摘要
为减少精油的无效挥发并延长持效期,采用界面聚合法,以异佛尔酮二异氰酸酯(IPDI)三聚体和二乙烯三胺为膜材,制备包含植物精油的微胶囊悬浮剂,并对赤拟谷盗进行了生物活性测定。结果表明:制备的微胶囊形貌在扫描电镜下近似圆球形。与植物精油相比,微胶囊化后的精油对赤拟谷盗仍有较好的活性,且持效期延长,表明微胶囊具有一定的缓释性。
In order to reduce the effect of the essential oil and extend the duration, microcapsule suspensions containing essential oils were prepared by interfacial polymerization with trimer of isophorone diisocyanate and diethyl enetriamine,and the bioactivity against Tribolium castaneum were also determined. The results showed that the microcapsules were spherical. Comparing with the essential oils,the microcapsule showed good bioactivity to Triboliurn castaneurn ,more importantly,the lasting period was extended.
