摘要

摘要: 通过磁控溅射将二氧化钛（TiO₂）沉积在涤纶织物表面形成薄膜，制备二氧化钛/涤纶（TiO₂/PET）抗紫外线功能织物，探讨制备过程中磁控溅射时间和溅射功率对织物抗紫外线功能的影响，分析TiO₂薄膜的紫外线吸收和屏蔽机理，同时检测织物隔热、热稳定性能的变化情况. 结果表明：在PET织物表面沉积TiO₂薄膜可改善织物的抗紫外线性能，归因于TiO₂薄膜对紫外光较好的吸收和对紫外可见光有效的屏蔽能力；且因TiO₂薄膜在溅射150 W以上的功率下粗糙度增加、厚度减少，当溅射功率为150 W，溅射时间为90 min时，TiO₂/PET织物具有较强的抗紫外线能力，其紫外线防护系数（Ultraviolet Protection Factor，UPF）达到1211.19；同时，TiO₂薄膜的沉积赋予了PET织物良好的热稳定性能和隔热性能.

Abstract: Titanium dioxide/polyester (TiO₂/PET) ultraviolet (UV) resistant fabric was prepared by deposition of titanium dioxide on the surface of polyester fabric by magnetron sputtering. The effects of magnetron sputtering time and sputtering power on the UV resistance of the fabric during the preparation process were investigated. The UV absorption and shielding mechanism of TiO₂ thin films were analyzed, and the thermal insulation and thermal stability of the fabric were also detected. The results show that TiO₂ film deposited on the surface of PET can improve the UV resistance of the fabric, which is attributed to the good UV absorption capacity of TiO₂ film and the effective shielding ability of UV visible light. In addition, the roughness of TiO₂ film increases and the thickness decreases when the sputtering power is greater than 150 W, so when the sputtering power is 150 W and the sputtering time is 90 min, TiO₂/PET fabric has the strongest UV resistance, and its UV protection coefficient (UPF) is 1211.19. Simultaneously, the deposition of TiO₂ thin film endows the PET fabric with good thermal stability and heat insulation performance.
