  • Method for forming imprinting roller
    Publication number: 20110132768
    Abstract: The invention relates to a forming method for imprinting roller. A photoresist layer is coated on an aluminum roller with cylindrical surface. After a pattern is transferred on the photoresist layer, the photoresist layer with the pattern is formed on the aluminum roller. Then the anodic oxidization treatment conducted for the photoresist layer with the pattern on the aluminum roller. Repeat the above-mentioned steps to obtain the roller with nanopore structure. When the roll-to-roll process is applied, the motherboard of roller with arbitrary size can be formed to facilitate the transfer printing of large area.
