超声波降解壳聚糖制备纸用微囊的研究

Application of Ultrasonic Degraded Chitosan to Prepare Microcapsule Used in Paper

通过超声波降解获得不同相对分子质量的壳聚糖,以其作为壁材进行包囊实验,考查了超声波降解壳聚糖机理及在成囊过程中微囊粒径分布规律,并且对成品微囊进行强度检测和使用实验,从而确定了制备纸用微囊所用壳聚糖的最佳超声波降解功率。

Chitosans with different molecular weight were obtained througb ultrasonic degradation. The chitosans were used as the wall material to prepare microcapsule in the experiment. The mechanism of uhrasonic degradation of chitosan and the distribution of microcapsule＇ s size were investigated. Also the strength of the resultant microcapsule was examined and its application experiment was carried out. Consequently, the best ultrasonic power of deading chitosan for pretesting microcapsule used in paper was decided.
