| 摘 要： | 采用以异丙醇为溶剂,以3-氯-2-羟丙基三甲基氯化铵(CTA)为改性剂,在碱性条件下制备了水溶性壳聚糖季铵盐。对其进行了吸湿、保湿性能的测试。壳聚糖季铵盐在相对湿度为43%的干燥器中放置48h吸湿率可达28.6%,水分残存率可达170.5%;在相对湿度为81%的干燥器中放置48h吸湿率可达54.2%,水分残存率可达615.2%;在硅胶干燥器中放置48h水分残存率可达82.4%。壳聚糖季铵盐的吸湿、保湿性能均优于同等条件下透明质酸的测定结果。

| Abstract: | Under the alkalescent condition,with isopropyl alcohol as the solvent and 3-chlorine-2-hydroxy propyltrimethyl ammonium chloride as the modifier,making up chitosan quaternary ammonium salt.test its moisture absorption and removing performance.The moisture absorption rate of chitosan quaternary ammonium salt can come to 28.6% when it is under 43% of relative humidity in the desiccator for 48 hours,and the rate of water remanet can come to 170.5%.The moisture absorption rate of chitosan quaternary ammonium salt can come to 54.2% when it is under 81% of relative humidity in the desiccator for 48 hours,and the rate of water remanet can come to 615.2%,the rate of water remanet can arrive 82.4% when in the silica gel desiccator for 48 hours.The moisture absorption and retentivition of chitosan quaternary ammonium salt were better than that of HA. |
