Embodiment 1

[0080] A PET film with a three-dimensional concave columnar array micro-nano texture template with a diameter of 2.5 μm and a depth of 300 nm is used as a transfer mold. The texture surface has an anti-sticking effect and does not adhere to the cured transfer UV glue.

[0081] Point the transfer UV glue line on the edge of the outer surface of the PMMA\PC composite board substrate, and then place the PET film of the transfer mold on the glue line substrate, the mold texture side faces the transfer UV glue, and the mold texture area Corresponds to the area where the substrate needs to be textured. Apply roller pressure on the outer surface of the transfer mold, and roll from one side of the dispensing line to the corresponding side, so that the transfer UV glue is completely filled between the texture surface of the transfer mold and the surface of the substrate.

[0082] Use a full-band UV surface light source with an energy of 360mJ to irradiate and transfer the UV adhesive l...

Abstract

The invention relates to a method for preparing a micro-nano structure on the surface of a base material, the base material with the micro-nano structure on the surface and application of the base material. Comprising the following steps: providing a base material and a micro-nano texture template with a micro-nano size and a three-dimensional structure; transfer printing UV glue is applied to the base material; the micro-nano texture template is applied to the transfer printing UV glue through UV transfer printing, then a transition glue layer is prepared through UV curing, the micro-nano texture template is removed, and an intermediate is prepared; and carrying out plasma etching on the intermediate by adopting an etching plasma source so as to remove the transition glue layer in a region to be etched on the surface of the base material, and etching a three-dimensional structure with a micro-nano size on the surface of the base material. The method has the advantages of being easy to operate, controllable in micro-nano structure morphology, low in cost, long-acting and capable of being applied on a large scale. In addition, the use of exposure and development can be reduced, and the equipment cost and the manufacturing cost are saved.
