摘　　要：为研究对壳聚糖进行氰乙基化改性后对纸质文物加固保护的可行性,将试验得到的壳聚糖改性产物配制成适当浓度的胶液,喷涂于纸样表面,分别进行抗张强度测试、耐折度测试、抗干热加速老化试验、光泽度测试等工作,并用FTIR进行表征。结果表明,经最佳浓度为30%的氰乙基壳聚糖胶液保护后,纸样保持了原有的质感、光泽、颜色,抗张强度提高了67%,耐折度提高了5.5倍。由此证明,氰乙基壳聚糖对纸质文物的加固保护效果明显,为天然高分子在文物保护中的应用开辟了广阔的前景。The study focused on the modification of chitosan by cyanoethylation. The product was dissolved in water at proper concentration and sprayed to the surface of paper. Tensile strength, folding endurance, glossiness, dry - heat ageing resistance and FT-IR tests were conducted on those samples. The results showed that the paper treated by 30% cyanoethylated- chitosan glue contained its origin feeling, glossiness and color, meanwhile compared to the untreated paper tensile strength was increased by 67 % and folding endurance was increased 5.5 times. It proves that cyanoethylated - chitosan has good effect on the protection of paper historic relic.
