A method of fabricating a hydrophilic-hydrophobic transformable composite film is provided. The method includes forming a silicon-containing layer on an iron-containing substrate; coating a titanium-containing sol-gel film on the said silicon-containing layer; and heating the iron-containing substrate with the silicon-containing layer and the titanium-containing sol-gel film thereon.

Method of fabricating hydrophilic-hydrophobic transformable composite film

A hydrophilic-hydrophobic transformable composite film is disclosed, which has an iron-containing substrate; a silicon-containing layer formed on the iron-containing substrate; and a titanium oxide layer formed on the silicon-containing layer. The hydrophilic-hydrophobic transformable composite film uses UV-light to switch its hydrophilic and hydrophobic property. Also, a method of fabricating the above composite film is disclosed. According to the present invention, an anatase oxide layer can be obtained from the sol-gel techniques, in which the particle size of the titanium dioxide is controlled and a modified surface coating with evident photo-catalyticity is achieved.
