Method for manufacturing roller having micro-nano structure

The present invention relates to a method of manufacturing a drum, and more particularly to a method of manufacturing a drum having a micro-nano structure.

In general, when a regular pattern is to be produced on an impression cylinder, two techniques are often used. One technique uses a diamond knife engraving method to continuously process the columnar body with a diamond knife to form a continuous pattern. However, this method of production is time consuming and expensive, and it is not easy to accurately control the accuracy and size of the pattern. Therefore, this technology is gradually being phased out.

Another technique for making a roller is to first define a pattern structure on a plane by means of lithography or diamond knife engraving, and then cover the pattern structure with a soft material, thereby duplicating the soft master and then applying the soft mother. The mold is attached to the columnar body. However, such a manufacturing method not only has a problem that it is difficult to attach the master mold to the columnar body, but also the mechanical properties of the soft master mold are poor and the durability is poor.

In addition, when this soft master is attached to the column, seam problems occur. Therefore, when the roller is used for embossing, the seam must be cut off, and thus it is impossible to emboss a continuous and large-area pattern by using the roller. Moreover, if it is desired to emboss a larger usable area, a larger area of the original mold is required. However, for large-area pattern definitions, lithography or diamond knife engraving can also create problems that are difficult to machine.

Accordingly, it is an aspect of the present invention to provide a method of manufacturing a roller having a micro-nano structure capable of directly forming a single and continuous micro-nano pattern on a columnar body in a self-assembled manner. Therefore, the formed roller mold has no seam problem and can be applied to imprint a continuous pattern.

Another aspect of the present invention is to provide a method for manufacturing a roller having a micro-nano structure, and a drum having a micro-nano structure can be produced without using a diamond knife engraving process or a lithography process. Therefore, the pattern uniformity can be improved, the process yield can be improved, the working hours can be shortened, and the manufacturing cost can be reduced.
