In order to find a new way to prepare antibacterial fibers , photocatalytic oxidation of titanium dioxide ( tio2 ) has been used to modify the surface property of polymers in our experiment . tio2 films are deposited on polyethylene terephthalate ( pet ) substrates by means of rf magnetron sputtering using pure ti ( 99 . 99 % ) as the target and ar mixed with o2 as reactive gas 本文利用磁控反應濺射技術,以高純度鈦( ti )為靶材,氧氣為活性氣體,在pet基底上反應濺射沉積tio _ 2 ,將納米tio _ 2的光催化氧化特性應用于高聚物表面改性,為進一步開發抗菌織物打下基礎。首次在高分子pet基底上濺射沉積了氧化鈦薄膜。
