摘要：采用甲壳素(CT)和羧甲基纤维素钠(CMC)为基质,与硅胶、无机盐氯化锂复合制备调湿材料,考察了基质配比、硅胶用量对调湿性能的影响,并利用红外光谱、扫描电镜对复合调湿材料的结构进行了表征。结果表明,在最佳配比m(CT)∶m(CMC)∶m(LiCl)∶m(硅胶)=2∶2∶2∶1所制得的调湿材料在25℃相对湿度分别为80%,60%和40%时,最大吸湿量可达到134%,70%和45%,添加硅胶的甲壳素和羧甲基纤维素钠基质复合调湿材料具有优异的吸放湿性能。
Humidity-controlling material was prepared with chitin and sodium carboxymethyl cellulose (CMC)as the matrix material,mixed with silica gel and LiCl.Factors influencing performance of humidity-controlling material have been investigated.The structure and performance of the materials were characterized by means of analytical methods,such as FT-IR and SEM.The results indicated that hygroscopic capacity of the humidity-controlling material when the material was prepared with CT,CMC,LiCl,silica gel in the ratio of 2∶ 2∶2∶ 1 in mass could reach 134%,70%,45% under different humidity (80%,60%,40% RH)respectively.It also had great moisture capacity.
