The Effect of Process Condition in Nano-molding on the Property of SAM (self-assembled monolayer)
- 발행 : 2005.10.01
초록
In this study, SAM (self-assembled monolayer) was applied as an anti-adhesion layer in the nano molding process, to reduce the surface energy between the nano-stamper and the moldeded polymeric nano patterns. Before depositing SAM on the stamper, the nickel stamper was pretreated to remove oxide on the nickel stamper surface. Then, using the solution deposition method, alkanethiol SAM as an anti-adhesion layer was deposited on nickel surface. To examine the effectiveness of the SAM deposition on the metallic nano stamper, the contact angle and the lateral friction force were measured at the actual processing temperature and pressure for the case of nano compression molding and at the actual UV dose for the case of nano UV molding. The surface energy due to SAM deposition on the nickel nano stamper markedly decreased and the high hydrophobic quality of SAM on the nickel stamper maintained under the actual molding environments.
