In this study, we examined the fabrication of polymer ultra-thin films (nanosheet) using a micro gravure printing method. Conveying speed of the plastic film substrate, the concentration of solution, rotating speed of the micro gravure roll was investigated experimentally for effects on the film thickness of the nanosheets. The PET film (thickness 100 μm, width 100 mm) as substrate was placed through roller. After that, the tension load was applied to film. And then, Polyvinyl alcohol (PVA) was coated on the PET film in order to release the nanosheets from the PET film by sacrificial layer method. After that, Polylactic acid (PLLA) was coated. Thickness of nanosheets was measured using a stylus type surface profile. Furthermore, In the field of micro / nano, nanoimprint technology which can press a mold having a pattern of irregularities of several tens [nm] level to the resin and transfer the pattern as it is attracts attentionin order to further enhance the functionality of the nanosheets, a nanosheets having a fine structure was produced using a hot press method and a roll thermal nanoimprinting method. As a result, since the shape of the mold could be transferred, it was possible to fabricate a nanosheets having a microstructure by roll nanoimprinting method.
