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。

Abstract: Low temperature RF magnetic sputtering is applied to deposit nano-structured film of TiO_2 and rare-earth Nd on the surface of PET nonwoven.Therefore,absorption spectrum of TiO_2 is widened and better anti-bacterial 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 TiO_2,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 TiO_2 film.And the AFM and XRD tests indicated that the crystal structure of the nano-sized laminated TiO_2/Nd film on the surface of PET nonwoven is of anatase form with better crystallinity and multi-layer growth mode.
