Abstract
A Braun tube having an antibacterial coating film, which is manufactured by the steps of dispersing titanium dioxide (TiO2) in alcohol to prepare a dispersion. Then, the dispersion is coated on a Braun tube, and a thermal treatment is then performed. By a photocatalytic reaction of the titanium dioxide contained in the antibacterial coating film, oxygen (O2) and water (H2O) in the air are decomposed into superoxides (O2−) and hydroxy radicals (OH·), which destroy bacteria and mold around the Braun tube and remove bad odor.
Claims3
A Braun tube including an antibacterial film consisting of TiO2 and a silicate in the ratio of about 1:1 to about 1:2.
A Braun tube including an antibacterial film consisting of TiO2 and a silicate, wherein the TiO2 has the structure of anatase and the average particle diameter is in the range of 1-50 nm.
A Braun tube including an antibacterial film consisting of TiO2 and a silicate, wherein the thickness of the antibacterial coating film is in the range of 500-5000 Å.
