  • Publication number: 20090191713
    Abstract: Provided is a method of forming a fine pattern using a block copolymer. The method comprises forming a coating layer including a block copolymer having a plurality of repeating units on a substrate. A mold is provided having a first pattern comprising a plurality of ridges and valleys. The first pattern is transferred from the mold into the coating layer. Then, a self-assembly structure is formed comprising a plurality of polymer blocks aligned in a direction guided by the ridges and valleys of the mold thereby rearranging the repeating units of the block copolymer within the coating layer by phase separation while the coating layer is located within the valleys of the mold. A portion of the polymer blocks are removed from among the plurality of polymer blocks and a self-assembly fine pattern of remaining polymer blocks is formed.

  • Patent number: 6576589
    Abstract: There is provided a method for preparing an anatase type titanium dioxide photocatalyst having a particle size of nano level without a need of the sintering process at high temperature, and an anatase type titanium dioxide photocatalyst having a particle size nano level. The method for preparing an anatase type titanium dioxide photocatalyst having a particle size of nano level includes adding a titanium-based starting material to a selected solvent and adding an acid or base catalyst to the resulting aqueous solution. Next, subjecting the catalyst-containing aqueous solution to heat treatment at about 80±20° C. to activate peptization thereby preparing an anatase type titanium dioxide sol solution. Finally, the anatase type titanium dioxide sol solution is coated onto a support to complete the preparation of the photocatalyst.
