Abstract
Summary form only given. The preparation of a high-functional polymer membrane inside the microchannel is one of the promising ways to integrate complicated chemical processes into microchips, which allows us a wide variety of applications in this research field. Here, we focus on the laminar flow formed inside the microchannel by the introduction of an organic solution and an aqueous solution to prepare the high-functional polymer membrane by interfacial polycondensation. In this study, we prepared a nylon membrane in the microchannel by interfacial polycondensation under the laminar flow condition.
