摘要：

将壳聚糖与丙烯酰胺和顺丁烯二酸进行接枝共聚，制得壳聚糖的接枝聚合物，并用红外、热重分析对其进行了表征。将其溶液体系涂敷于聚丙烯无纺布上，随后对涂层织物进行了断裂强力测试、结合牢度测试、热差分析以及Pb2 +的吸附和解吸附实验。结果表明，丙烯酰胺和丁烯二酸成功地接枝到了壳聚糖上，而且引起了壳聚糖分子结构的变化；涂层织物的结合牢度高，断裂强力明显增加；该涂层织物对铅离子的吸附性比纯壳聚糖涂敷织物提高了大约28%；解吸附实验中，分别用HNO3和HCL做解吸附溶液，经过3次解吸附，涂层织物在溶液中的解吸率分别达到了93.4%和65.5%。

Abstract:

Chitosan, Acrylamide,Maleic acid as raw materials,we synthesized a kind of graft copolymer about chitosan . It is characterized through Infrared spectrum (IR) and TG .Then the solution system of graft copolymer is coated on the PP non-woven fabric.We characterized the performance of coated fabric by tensile property test、combile fastness and DSC subsequently .The adsorption and desorption capacity of Pb2 + with the coated fabric were studied in the following tests.The results showed that: Acrylamide and Maleic acid are successfully grafted onto the chitosan and the molecular structure of chitosan has changed.The coated fabric has good combile fastness ,the tensile property improved evidently;The adsorption capacity for Pb2 + of the coated fabric is higher than the coated fabric of chitosan about 28%；In the desorption test,the desorption rates for Pb2 + are 93.4% and 65.5% with HNO3 and HCL after 3 times of desorption test.
