摘　　要：采用低温射频磁控溅射技术在PET基非织造布表面沉积TiO2与稀土Nd的纳米结构复合薄膜,以宽化纳米TiO2的吸收光谱,使其在可见光照射的情况下具有较好的抗菌效果,实现纺织材料表面的抗菌功能化。利用振荡烧瓶法分别测试了TiO2薄膜、稀土Nd薄膜以及TiO2与稀土Nd复合薄膜的抗菌性能。实验结果表明:在纳米TiO2薄膜中掺杂一定量的稀土Nd可有效提高其抗菌性能。XRD、AFM等测试结果表明,PET非织造布基材上沉积的纳米结构TiO2/Nd复合薄膜为结晶度较好的锐钛矿型TiO2,生长模式是多层生长形式。Low temperature RF magnetic sputtering is applied to deposit nano-structured film of TiO2 and rareearth Nd on the surface of PET nonwoven. Therefore, absorption spectrum of TiO2 is widened and better antibacterial performance under visible light is conferred. In this way, the anti-bacterial function of surface is realized for textile material . The anti-bacterial performances of nonwovens covered with nanosized films of TiO2, Nd and laminated component were measured by shake flask test. The results showed that a certain quantity of rare-earth Nd can effectively improve the anti-bacterial performance of nano-sized TiO2 film. And the AFM and XRD tests indicated that the crystal structure of the nano-sized laminated TiO2/Nd film on the surface of PET nonwoven is of anatase form with better crystallinity and multi-layer growth mode.
