Replication/transfer of self-assembled particles by imprint process (2nd report)

Influence of imprint pressure on replication/transfer mechanism

Abstract

Close-packed structures of fine particles can be self-assembled by dip coating with suspension that contains particles. By using imprinting process, the assembly profile can be replicated or the particles themselves can be transferred to another substrate. This study aims to clarify the effects of imprinting pressure on imprinting process with UV curing resin. It was found that the replication rate that shows the depth/width of replicated profile or transferred rate that shows the depth/width of buried in resin can be changed by the imprinting pressure as well as homogeneity of the structure.
