Rolling mold for microstructured film imprinting

Abstract

A rolling mold for microstructured film imprinting includes a roller and a filmed metal template. The roller has a round outer surface. The filmed metal template is disposed with a microstructured film imprint pattern and changeably coupled to the roller by magnetic force or vacuum suction. Rolling of the roller allows the microstructured film imprint pattern to form a microstructured film, thus solving the drawbacks of the prior art.
