近年来，随着抗菌制品需求的增加，人们开发了各种各样的抗菌剂，包括有机和无机两大类，各有特点．氧化钛是基于光催化反应使有机物分解而具有抗菌效果．其特点是即效性，如银系抗菌剂的效果约在24h左右发生，而氧化钛仅需出左右．第二个特点是氧化钛是一种半永久维持抗菌效果 In recent years, with the increasing demand of antibacterial products, a variety of antibacterial agents have been developed, including organic and inorganic, with their own characteristics. Titanium oxide is based on the photocatalytic reaction of organic matter decomposition has antibacterial effect. Its characteristics are immediate effect, such as the silver antibacterial agent effect occurs about 24h or so, and titanium dioxide only about out. The second characteristic is that titanium oxide is a semi-permanent antibacterial effect
