以甲壳素为原料,制备了甲壳素基微球新型卫生材料;采用核磁氢谱、红外和扫描电镜对其结构进行表征,测试并分析了甲壳素基微球的溶胀性、生物相容性和抗菌性能。结果表明,微球Qc1~Qc6均具有很强的吸水性能;Qc3的分散度为0.337,相对其他甲壳素基微球在水中的分散性更小,不易聚集成团。因Qc3所含的季铵化甲壳素的质量分数更大,展现的抑菌效果更好。各方面的评测结果显示,该可降解甲壳素基微球有望替代不可降解的尿不湿填料。

In order to solve the problem that super absorbent polymer,the main material of diapers on the market,is difficult to degrade,chitin is used to prepare chitin-based microspheres as a new sanitary material.The structure of chitin-based microspheres is characterized by nuclear magnetic resonance (¹HNMR),infrared absorption spectrum (IR) and scanning electron microscope (SEM).The swelling performance,biocompatibility and antibacterial properties of chitin-based microspheres are measured and analyzed.It is shown that the microspheres from Qc1 to Qc6 have strong water absorption properties.The polymer dispersity index of Qc3 microspheres in water is 0.337,lower than that of other chitin-based microspheres.Qc3 microspheres are not easy to agglomerate.Because Qc3 microspheres contain a larger percentage of quaternized chitin,they show good antibacterial efficacy.It is shown through various test and evaluation that these degradable chitin-based microspheres are expected to replace non-degradable diaper filler.
