UV-Curable Technique of Magnetic Roller Soft Mold and Microstructure Pattern Replication

This study adopted the novel magnetic roller soft mold embossing technique of the soft mold preparation method, embossing, combined with the existing gas-assisted UV-curable technique, to develop an innovative magnetic-assisted continuous roller platform. Using the advantages of uniform and accurate control of applied pressure of the magnetic disk, this study used the magnetic roller soft mold embossing and UV-curable technique for replicating microstructure patterns, resulting in a more mature micro-nano embossing technology and application. The experimental results showed that the new magnetic roller soft mold preparation method can accurately cast and replicate micro-nano structures of Polydimethylsiloxane (PDMS) composite magnetic iron powder, and the magnetic disk can impose uniform pressure to effectively implement complete filling during the rolling process. This innovative process provides a simple and rapid molding mechanism, which significantly improves the microstructure pattern replication technique.
