在壳聚糖的分子链上接枝丙烯酸后添加无机盐,制得调湿材料。研究了实验因素,如无机盐的种类、无机盐用量对调湿材料的调湿性能影响。结果表明:无机盐选用K2CO3,用量占总量的25%时,调湿材料在相对湿度为30%、50%、70%下吸湿量分别可达11.1%、29.1%和47.6%,同时具有较好的放湿能力。 Grafted acrylic acid in the molecular chain of chitosan after adding inorganic salts to prepare humidity-controlling materials. The experimental factors such as the types of inorganic salts and the amount of inorganic salts on the humidity-controlling properties of humidity-controlling materials were studied. The results showed that when K2CO3 was used as the inorganic salt, the amount of moisture absorbed by the humidity-controlling materials reached 11.1%, 29.1% and 47.6% at the relative humidity of 30%, 50% and 70%, respectively, Good wet capacity.
