Abstract: The present invention relates to a method for manufacturing a three-dimensional structure based on a block copolymer. The method comprises the steps of injecting a block copolymer (BCP) solution into each micro-well formed on the substrate and drying it to form a block copolymer layer, and applying a buffer to the block copolymer layer to hydrate the micro-well in three dimensions Forming the structure, after the three-dimensional structure is formed, injecting and curing a hydrogel solution around the three-dimensional structure may include the step of enhancing stability. In particular, the process of hydration by applying a buffer to the micro-well is performed while an electric field is applied. By controlling the concentration of the block copolymer (BCP) and the amplitude and frequency of the electric field, a three-dimensional artificial cell membrane having a desired size and shape, such as a spherical or ciliary shape and high stability (100% survival for 50 days) is manufactured can do. The present invention can be efficiently applied to various biological fields such as artificial cells, cell-mimicking biosensors, and bioreactors.

Abstract: The present disclosure relates to a polyarylene ether-based polymer for an electrolyte membrane of a fuel cell, represented by the following Chemical Formula 1. When the polyarylene ether-based polymer for an electrolyte membrane of a fuel cell is applied to the manufacture of a membrane-electrode assembly through a decal process, the hot pressing temperature may be controlled to about 120° C. so as to conform to a low glass transition temperature. Therefore, it is possible to solve the problems of deterioration of an electrolyte membrane or incomplete transfer of an electrode catalyst layer, caused by the high hot pressing temperature applied in the case of the conventional hydrocarbon-based polymer material.
