Benefits of technology
Moreover, the invention provides a method for forming nano-imprinting roller, wherein the micro or sub-micro structure is generated on the surface of aluminum roller. It can solve the problem of flexible roller formed by the molding process, in which the surface structure is easy to be peeled off.
Problems solved by technology
However, this process is time consuming, and the size of product in limited by the dimension of motherboard.
Thus, the fast and continuous production is unable to be achieved.
Most rollers with micro-structure need very expensive equipments, and the process is very tedious.
However, as for the roller wrapped by thin metal sheet normally, the adherence of thin metal sheet will not be very close and tight.
Thus, the problems such as mold displacement, warping and the like during imprinting will be occurred usually.
There are problems such as insufficient strength and high-temperature deterioration during imprinting for the flexible roller formed by the molding process.
But because the anodic oxidization treatment needs a uniform electric field, so the micropores or nanopores will not be easy to be formed on the curved surface of cylinder or roller.

Embodiment Construction
FIG. 1A, FIG. 1B, FIG. 1C and FIG. 1D show the cross-sectional diagram of roller according to the embodiment of the invention. The detail is described as follows.
The method for forming imprinting roller as shown in FIG. 1A, a conductive roller 10 is provided. The geometrical shape is cylindrical, thus the cross-section is circular. The cylinder may be solid cylinder or hollow cylinder. The collected material may be aluminum or the aluminum alloy, the electroplated aluminum materials, the conductive materials, or the other alloy formed on the surface of conductive roller 10. In the embodiment of the invention, the aluminum made conductive roller 10 is used for the description, however, the invention is not limited by the above-mentioned. Moreover, in order to obtain better structure in the follow-up procedure, a polishing treatment is conducted on the surface of conductive roller 10.
Referring to FIG. 1B, a photoresist layer 12 is formed on the surface of conductive roller 10. In an e...

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.
Description
BACKGROUND OF THE INVENTION1. Field of the InventionThe invention relates to a method for forming imprinting roller, particularly to a method for forming nano-imprinting roller.2. Description of the Prior ArtThe imprinting technology has been evolved from microimprinting to nano-imprinting. In recent years, different processes have been developed successively. For example, in the photoresist coating technology, the structure on the flat motherboard is printed on the photoresist layer of substrate, and then it is cured by ultraviolet radiation. However, this process is time consuming, and the size of product in limited by the dimension of motherboard. Thus, the fast and continuous production is unable to be achieved.In addition, in another example, the structure is formed on the roller by roller imprinting, or wrapped by thin metal sheet with micro-structure, or formed by the molding process, and then the structure is transferred onto substrate.The roller microimprinting has the adva...
