石墨烯对涤纶织物整理及功能性研究

Finishing of Polyester Fabric with Graphene and the Function Study

文中首先使用氢氧化钠对涤纶织物进行碱减量处理使其表面亲水化,然后采用传统的浸-轧-烘干工艺将氧化石墨烯整理在其表面,最后经过还原反应后使得织物表面的氧化石墨烯被还原成石墨烯,制得功能性石墨烯整理涤纶织物。结果表明,使用涤纶织物碱处理可以促进氧化石墨烯在涤纶表面的负载,且其表面石墨烯的负载量随减量率的升高而逐渐增加。根据最优工艺制得的石墨烯整理涤纶织物具有性能良好的导电性和抗菌性能,通过增加减量率的方法可以使整理涤纶织物的功能性有所提高。

In this paper,firstly,the polyester fabric was alkali-reduced with sodium hydroxide to improve the surface hydrophilicity,and then the conventional dip-rolling-drying process was used to finish the graphene oxide on the surface,and finally the surface of the fabric was reduced after the reduction reaction.The graphene oxide is reduced to graphene to obtain a functional graphene-finished polyester fabric.The results show that the polyester fabric treatment with alkali can promote the loading of graphene oxide on the surface of polyester,and the loading of graphene on the surface gradually increases with the decrease of the reduction rate.The graphene-finished polyester fabric prepared according to the optimal process has good electrical conductivity and antibacterial property,and the functionality of the finished polyester fabric can be improved by increasing the reduction rate.
