智能高吸水保水材料与制备方法及在沙漠化治理中的应用
摘要：
一种智能高吸水保水材料，由NIPAAM-co-CMC和壳聚糖组成，NIPAAM-co-CMC的质量百分数为20％～95％，壳聚糖的质量百分数为5％～80％，所述NIPAAM-co-CMC是由N-异丙基丙烯酰胺与羧甲基纤维素聚合形成的聚合物。一种智能高吸水保水材料的制备方法，以N-异丙基丙烯酰胺、羧甲基纤维素和壳聚糖为原料，N-异丙基丙烯酰胺与羧甲基纤维素的质量比为0.02～0.3∶1，壳聚糖与羧甲基纤维素的质量比为0.053～4.08∶1，工艺步骤如下：(1)N-异丙基丙烯酰胺与羧甲基纤维素的聚合；(2)聚合反应产物和壳聚糖的复合。
摘要（英）：

The invention discloses an intelligent high water absorption and waterholding material, which consists of 20 to 95 percent of NIPAAM-co-CMC (N-isopropyl acrylamide-co-carboxymethylcellulose) and 5 to 80 percent of chitosan in percentage by mass, wherein the NIPAAM-co-CMC is a polymer formed by N-isopropyl acrylamide and carboxymethylcellulose. The invention also discloses a preparation method forthe intelligent high water absorption and waterholding material. In the method, the N-isopropyl acrylamide, the carboxymethylcellulose and the chitosan are used as raw materials, the mass ratio of the N-isopropyl acrylamide to the carboxymethylcellulose is 0.02-0.3:1, and the mass ratio of the chitosan to the carboxymethylcellulose is 0.053-4.08: 1. The method comprises the following steps of: (1) polymerization of the N-isopropyl acrylamide and the carboxymethylcellulose; and (2) compounding of the polymerization reaction product and the chitosan.
