摘要：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。
A humidity controlling material was prepared by graft copolymerization of chitosan with acrylic acid and mineral salt. The effect on capability of humidity controlling material was determined. Experimental results showed that adsorption in percent of humidity controlling material was 11.1%;29.1%;47.6% respectively in RH30%; RH50% ;RH70% and it was of well desorption capability.
