Ag-Ce共掺ZnO纳米棒及在改性涤纶织物上的应用

Preparation of Ag-Ce co-doped ZnO Nanorods and Application on Modified Polyester Fabrics

本研究以AgNO 3,(NH 4)2Ce(NO 3)4,Zn(NO 3)2·6(H 2O)和C 6H 12 N 4为原料,聚乙二醇2000为形貌控制剂,用低温水浴法在改性涤纶织物表面生长出Ag/Ce共掺的ZnO纳米棒,并且使用KH560作为偶联剂,提高掺杂ZnO纳米棒与改性聚酯织物之间的结合度。采用包括紫外-可见光漫反射(DRS)等多种技术手段对制备的样品进行表征分析和研究。结果表明:采用所研究方法可以将Ag/Ce元素均匀地涂覆在ZnO纳米棒上,具有良好的光催化性能,在紫外光下照射2 h,对MB溶液的降解率为93.14%;此外,整理后的改性涤纶织物的UPF值由30.4增加到50+以上,因此应具有良好的抗紫外线效果。

Ag/Ce co-doped ZnO nanorods were grown on the surface of modified polyester fabric by a method of low temperature water bath,in which AgNO 3,(NH 4)2Ce(NO 3)4,Zn(NO 3)2·6(H 2O)and C 6H 12 N 4were used as raw materials and polyethylene glycol 2000 as morphology control agent.In order to improve the bonding fastness between the doped ZnO nanorods and the modified polyester fabric,KH560 was used as a crosslinking agent.The prepared samples were characterized and analyzed by some methods including diffuse reflectance spectrum(DRS).The results show that Ag/Ce is uniformly coated on the ZnO nanorods and has good photocatalytic performance.Exposing to ultraviolet light for 120min,the degradation rate of MB is 93.14%.The UPF of modified polyester fabric after finishing is increased from 30.4 to 50+,Indicating that it has a good UV resistance.
