纳米氧化铈在棉织物表面的原位合成及其抗紫外性能

In-situ synthesis of nano-ceria on cotton fabric and its UV resistant performance

通过一种简单的原位合成法在棉织物的表面生成CeO2纳米粒子,并且采用SEM、XRD等方法对纳米粒子进行表征,UV-Vis测试发现,这些CeO2纳米粒子对棉织物的抗紫外性能有明显的提高。原位合成方法使得CeO2纳米粒子与棉织物的表面具有很强的化学键连接,因此,这种具有强抗紫外线功能的棉织物在水洗多次后仍然具有非常优异的抗紫外功能。本方法为纳米功能织物的工业化应用提供了一种可行的途径。

A simple in-situ synthesis method was used to prepare nano-ceria on the surface of cotton. TEM, SEM and XRD were used to characterize these cerium oxide nanoparticles, and the testing results of UV-Vis illustrated that these nano-ceria could improve the UV resistant property of cotton very clearly. These CeO2 nanoparticles have very strong connection with the surface of cotton based on the in-situ synthesis method, which make the UV resistant performance of cotton can maintain for a very long time even washed by water. This method applie an possible way for industry application of nano-functional fabric.
