Abstract
Close-packed structures of fine particles can be obtained by self-assembly process such as dip coating in which substrate is drawn-up from suspension that contains dispersed particles. By using imprinting process with resin, replication of the assembled profile or transfer of the assembled particles onto another substrate is possible. However, the effects of particle diameter, properties of resins and conditions in imprinting have not been made clear. This study focuses on UV-curing resin for imprint and makes clear the effects of above factors on the performance from the standpoint of profile accuracy. It was found that the affinity of resin properties have strong effects on the replication/transfer.In the case of material transfer, a resin penetrated into space between particles to the depth of about 60-90% of the particle diameter. In the case of shape replication, another type of resin was applied and it penetrated into the space to the depth of about 10-20% of particle diameter.
