摘　　要：对壳聚糖进行羧甲基化,通过提高其水溶性及高分子性能,根据单凝聚法以羧甲基壳聚糖作为微囊壁材,结晶紫内酯作为芯材进行包囊,考察了羧甲基化后的壳聚糖对制备纸用微囊粒径及其均一性的影响。In this thesis , chitosan showed that its water solubility, film - making ability were better than unmodified chitosan through carboxyl methylation. According to single cogulation process, this kind of microcapsule was made from carboxyl methylation chitosan as wall, crystal rider lactone as core. It was also studied that the influence of carboxyl - methylation on the size of microcapsule distribution and homogeneity.

关 键 词：壳聚糖 羧甲基化 微囊 均一性
