This study proposes an integrated imprinting technology, of combining gas-aided imprinting technology and gray-scale, regulated, electromagnetic, force hot-imprinting technology, for the replication imprinting forming of the curved surface micro-nano structure. Based on the existing gas-aided hot imprinting forming technology, this study designed an electromagnetic disc that can regulate and control the imprinting force at different positions, and with features of even and precise control of gradual pressure. The electromagnetic disc was integrated with the gas and the electromagnetic force aided hot-imprinting technology to replicate micro-structure, to make the micro-nano imprinting technology and applications more mature. The experimental results showed that the proposed integrated imprinting technology can accurately replicate the curved surface micro-nano micro-structure.

“…Because iron oxide exhibits permanent magnetism, PDMS-iron oxide nanocomposites (PIONs) are generally magnetic stimuli-responsive materials. Thus, the PIONs can be simply attached to a magnet or detached from it [13]. A more interesting application of the magnetism of such nanoparticles is rapid heating.…”

In the present study, the compressive behavior of polydimethylsiloxane (PDMS)-iron oxide nanocomposites (PIONs), particularly the effects of the iron oxide nanoparticle content and surfactant, was investigated. PIONs have been employed in various micro-and nano-engineering applications due to their advantageous properties. However, characterization of the mechanical characteristics is still insufficient, thereby limiting wide-spread application. In this regard, a compression test was carried out to evaluate the fundamental compressive behavior of the PION. The specimens were prepared by changing the content of the iron oxide filler and by modulating the surface energy of the PDMS matrix using a surfactant. From the stress-strain characteristics, the relationship between the compressive elastic modulus and iron oxide content was found to be linear. In addition, the native PION exhibited around 73.5% greater increase in the normalized compressive elastic modulus than the surfactant-treated PION, showing a negative effect of the increased surface energy.

This study proposed a type of innovative imprint replica process technique, by first developing a magnetic-aided roller microtransfer replica process equipment, and then using polydimethylsiloxane soft mould composite magnetic powder to create a roller for transfer imprint. Using the advantage of the even pressing of a magnetic roller, a microstructure array was used in this innovative manufacturing process for transfer replication study. Research results showed that, the magnetic-aided roller microtransfer machine developed in this study could successfully transfer a roller structure to polycarbonate film, thus resulting in an imprint effect. This study successfully applied this innovative manufacturing technology on a rolling microstructure array, and examined its replicability.
