An antibacterial article with long-lasting antibacterial effect for various environments is provided. The antibacterial article includes a substrate, a plurality of titanium dioxide layers and a plurality of Cu layers formed on the substrate. Each one of the titanium dioxide layers and each one of the Cu layers are deposited on each other. The titanium dioxide layer can lead the Cu ions release slowly, so the antibacterial article has long-lasting antibacterial effect. Antibacterial effect mainly relies on Cu layers without light. Under the light conditions, the titanium dioxide layer can also play its role and strengthen the antibacterial effect. A method for making the antibacterial article is also provided.本發明提供一種具有持久抗菌效果且適用多種環境的抗菌鍍膜件,其包括基材,形成於基材表面的複數二氧化鈦層和複數金屬銅層,該複數二氧化鈦層和複數金屬銅層交替排布。所述二氧化鈦層對金屬銅層中銅離子的快即溶出起到阻礙作用,從而可緩釋銅離子的溶出,使金屬銅層具有長效的抗菌效果;同時所述抗菌鍍膜件適用於多種環境,在沒有光照的條件下,抗菌鍍膜件主要依靠金屬銅層起到抗菌效果,在光照的條件下,二氧化鈦層可發揮其抗菌效果,使抗菌鍍膜件具有更強的抗菌效果。此外,本發明還提供一種所述抗菌鍍膜件的製備方法。10...抗菌鍍膜件11...基材13...打底層15...二氧化鈦層17...金屬銅層
