A study on high aspect ratio of plastic nano hair molding
고세장비 플라스틱 나노헤어 성형에 관한 연구
Abstract
High aspect ratio of nano hairs on a plastic substrate is molded using thermoplstic materials including COC, PP, PC and PMMA. As a template for molding nano hairs, AAO membrane is adopted, which is 60um thick and 13mm in diameter. This membrane has about 109 of through-holes of which diameter is around 200nm. This AAO membrane and the pellet of materials are stacked in the mold and pressed to mold after heating up to be melted. The AAO membrane is removed using KOH to obtain the molded nano hairs. As a result, the diameter of the molded hairs is around 200nm and the length is
