摘要 利用KH560交联剂来提高La-Gd/ZnO纳米棒阵列在棉织物上的牢度。以硝酸锌和六亚甲基四胺为原料,聚乙二醇2000为形貌控制剂,KH560为交联剂,采用低温水浴法制备在棉织物表面原位生长的La-Gd/ZnO纳米棒阵列。同时利用X射线衍射仪、扫描电子显微镜和紫外-可见光漫反射等方法对制备的样品进行表征和性能分析。结果表明:3% La-3% Gd/ZnO纳米棒具有良好的光催化性能,在紫外光下照射150 min,对亚甲基蓝溶液(MB)的降解率为92.15%;太阳光下照射8 h,对亚甲基蓝溶液(MB)的降解率为87.59%。且经过整理后的棉织物的抗紫外线指数UPF值由10.06提升至420.21。经水洗10次,其光催化性能仅下降1.3%,抗紫外线指数基本没有变化。

Abstract: KH560 is used as crosslinking agent to improve the fastness of La-Gd/ZnO nanorod arrays on the surface of cotton fabrics.La-Gd/ZnO nanorod arrays grow in-situ on the surface of cotton fabrics through low temperature hydrothermal method by using zinc nitrate and hexamethylene tetramine as raw materials,polyethylene glycol 2000 as morphology control agent and KH560 as crosslinking agent.The prepared samples are characterized by XRD,SEM,UV-siv and other measurements.The analysis results show that cotton fabric modified by 3% La-3% Gd/ZnO nanorod arrays performs excellent anti-ultraviolet and photocatalytic properties,and its anti ultraviolet index-UPF increases from 10.06 to 420.21 after modification.The degradation rate of methylene blue solution reaches 92.15% under irradiation of ultraviolet for 150 min with the presence of as-prepared catalyst,and that reaches 87.59% under irradiation of solar light for 8 h.After 10 times of washing by water,the photocatalytic performance of the prepared catalyst only decreases by 1.3% and its UPF remains unchanged,reflecting its good fastness.
