| abstract |
A precipitated film and the fabricating method thereof are disclosed. The precipitated film includes a supporting layer having columnar crystals, and a functional layer formed on the supporting layer and having granular crystals. The precipitated film is fabricated by phase-changing one of two aqueous solutions, which are able to react with each other to form a solid precipitate inherently, into solid-state and then reacting with the other aqueous solution to form the precipitated film by a precipitation reaction. |
