中文摘要：
根据多孔树脂结构的设计,利用二次致孔法制备了CMC-g-PAM/PAAS多孔树脂。通过TG、SEM、FTIR、XRD和氮气吸附法等手段表征了该树脂的形貌和结构特征,测试了多孔树脂分别在高湿和低湿条件下的调湿平衡和最大湿含量,分别讨论了绝对湿度变化条件和温度变化条件下多孔树脂的调湿性能。结果表明,AlCl3的质量分数为丙烯酰胺单体的2.5%时,多孔树脂的调湿平衡范围为57.5%～62.5%,最大湿含量为自身质量的122%。在绝对湿度变化条件下,多孔树脂仍能维持相对湿度在57.5%～62.5%范围之内;在温度变化条件下,多孔树脂在40℃时的调湿平衡时间不超过1h,在10℃时的调湿平衡时间不超过3h。
英文摘要：
According to the structural design of porous resin,CMC-g-PAM/PAAS porous resin was prepared by the twice foaming method.The morphology and structure properties of the resin were characterized by thermogravimetry（TG）,scanning electron microscopy（SEM）,X-ray diffractometer（XRD）,Fourier transform infrared spectroscopy（FTIR） and nitrogen adsorption.Humidity-controlling capability and maximum moisture content of the porous resin were tested under high humidity and low humidity conditions.Humidity-controlling capability was investigated at changing absolute humidity and temperature.The results showed that when aluminum chloride was 2.5%（mass） of the acrylamide monomer,the porous resin showed a humidity-controlling range of 57.5%—62.5%,its maximum moisture content was 122% of its own mass.The porous resin was able to maintain relative humidity in the range of 57.5%—62.5% also in the case of changing absolute humidity.The porous resin reached equilibrium humidity in less than 1 h at 40℃ and in less than 3 h at 10℃.
