中文摘要：
通过醋酸和混酸（V_（浓硫酸）∶V_（浓硝酸）=3∶1）两种方法对碳纳米管进行改性,然后在制备再生纤维素的基础上,制备改性碳纳米管-再生纤维素膜。通过红外、XRD和结构等对碳纳米管及其碳纳米管改性再生纤维素膜进行了性能表征,混酸能使碳纳米管表面接上羟基和羧基,同时去除表面杂质,引入碳纳米管能改变再生纤维素膜的结构和结晶性能。
英文摘要：
Carbon nanotubes were modified by two methods of acetic acid and mixed acid（ V_（sulfuric acid）∶V_（nitric acid）= 3∶1）.On the basis of the preparation of regenerated cellulose, the modified carbon nanotubes- regenerated cellulose membrane was prepared. By IR,XRD and structure properties of carbon nanotube characterization,mixed acid can make the surface of carbon nanotubes grafted in hydroxyl and carboxyl,at the same time to remove surface impurities.The structure and crystalline properties of regenerated cellulose membranes can be changed by the introduction of carbon nanotubes.
