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.
