摘　　要：用环氧丙烷等作醚化剂,在碱性条件下对壳聚糖进行接枝改性。试验得到的壳聚糖改性产物———羟丙基壳聚糖具有良好的水溶性,配制成适当浓度的胶液,喷涂于纸样表面,进行抗张强度测试、耐折度测试、抗干热加速老化试验、光泽度测试等一系列试验,结果表明,纸样保持了原有的质感、光泽、颜色,抗张强度提高了近一倍,耐折度也有提高,羟丙基壳聚糖对纸质文物的加固保护效果明显。Chitosan was modified by epoxy propane to prepare O-(hydroxyl isopropyl) chitosan (HPCS). HPCS, the water soluble product, was dissolved by water and sprayed the surface of paper. Through tensile strength, folding endurance, glossiness and dry-heat ageing resistance tests, results showed that the tensile strength increased nearly 100% and the folding endurance also increased. Moreover, the paper by HPCS treatment remained former handle, gloss and color. All of the results proved that the HPCS was useful in the protection to the paper-based relics .
