摘　　要：为解决光催化降解技术中光催化剂制备方法复杂和降解效率低的问题,以棉织物为基底,采用浸渍法将MXene粉末均匀附着在棉纤维上,制得MXene功能棉织物。其在可见光下150 min内,光催化降解亚甲基蓝的效率达到97.7%,且经过三次循环降解后,对亚甲基蓝的降解效率仍达到97%。MXene功能棉织物的UPF值远大于50,且T(UVA)为0.05%,表现出优异的抗紫外性能。In order to solve the problems of complex preparation methods and lower degradation efficiency of photocatalyst in photocatalytic degradation technology,cotton fabric is used as the substrate,and MXene pow⁃der is uniformly adhered to cotton fibers by impregnation method.The photocatalytic degradation efficiency of Methylene Blue reaches 97.7%within 150 min under visible light,and the degradation efficiency of Methylene Blue still reaches 97%after three cycles of degradation.The UPF value of MXene functional cotton fabric is much greater than 50,and T(UVA)is 0.05%,showing excellent UV resistance.
