제목 Large-scale Continuous Printing of Semiconducting Polymers by Meniscus Oscillated Evaporative Self-Assembly
초록 Evaporative self-assembly of semiconducting polymers has been an emerging technology to construct hierarchical patterns toward flexible organic electronics. However, its practical application has been limited due to the non-continuous time-consuming process. In this presentation, we report a high-throughput continuous printing of hierarchical structured poly (3-hexylthiophene 2,5-diyl) (P3HT) by a custom apparatus. The oscillation of roller with a stage heating creates centimeter-scale periodic lines of P3HT by repetitive stick and slip phenomenon of meniscus within one minute. In addition, the MOSA process enhanced crystallinity of P3HT revealed by a grazing incidence wide angle X-ray scattering (GIWAXS). Remarkably, the meniscus oscillated self-assembly (MOSA) demonstrate wide range of engineering capability: nanometer scale thickness, micron scale width, sub-millimeter scale pattern intervals, and millimeter to centimeter scale length with highly defined boundaries.
