マイクログラビア印刷方式を用いた高分子超薄膜の創製

抄録

In this study, we fabricated poly (lactic acid) nanosheet, that thickness is less than 100 nm, by using micro gravure printing. Nanosheet has several unique characteristics compared with bulk films, the large aspect ratio of such nanosheets leads to unique physical properties, such as transparency, noncovalent adhesion, and high flexibility. We investigated the effects of film transportation speed, rotational speed of micro gravure roll and solution concentration on film thickness of nanosheet fabricated by micro gravure printing. Moreover, physical property of nanosheets fabricated by micro gravure printing and spin coat methods were compared.
