摘要： 利用过氧化氢对壳聚糖进行氧化降解,获得了一系列不同黏均分子量的壳聚糖。用不同黏均分子量的壳聚糖对纸张表面进行施胶,研究施胶对纸张性能的影响。结果表明:壳聚糖黏均分子量的降低不利于其表面施胶效果,并通过扫描电镜图进行了证实;在相同条件下,相比于单独使用氧化淀粉,少量壳聚糖与氧化淀粉共混作用于纸张表面,对纸张表面强度增强效果更佳。

关键词: 壳聚糖, 降解, 表面施胶, 氧化淀粉

Abstract: A series of chitosan of different viscosity-average molecular weight were prepared by oxidation of chitosan with hydrogen peroxide as the oxidizing agent.The chitosan of different viscosity-average molecular weight was applied as paper surface sizing agent,and the effect to the surface properties of the paper was studied.Results showed that the reducing of chitosan viscosity-average molecular weight is not beneficial to its surface sizing effect.Such result was confirmed by SEM.Under same conditions,as comparing with using oxidized starch alone,the mixture with a small amount of chitosan and oxidized starch can improves the surface strength of paper obviously.

Key words: chitosan, degradation, surface sizing, oxidized starch
