Abstract: Disclosed is a method of manufacturing an organic semiconductor thin film, including preparing semiconductor ink containing a solvent, a low-molecular-weight organic semiconductor and a high-molecular-weight organic semiconductor and forming an organic semiconductor thin film vertically phase-separated by applying the semiconductor ink on a substrate through a bar-coating process using a bar. In the bar-coating process of the invention, the semiconductor ink blend is used, and the gap between the substrate and the bar is adjusted, thus controlling vertical phase separation. Also, the speed of the bar, the gap of which is adjusted, is regulated, thus controlling crystal growth, whereby the uniformity of the thin film is improved and thus a high-quality organic semiconductor crystalline thin film having a large area can be manufactured in a continuous process. Also, a flexible organic semiconductor transistor, having high stability and high charge mobility, can be provided using the organic semiconductor thin film.

Abstract: Disclosed is a method of manufacturing a surface-modified polymer film, including forming a hydroxyl group (—OH) on the surface of a polymer film by subjecting the polymer film to light irradiation and surface treatment with a photoacid generator. The polymer film can be introduced with a hydroxyl group (—OH) group using a photoacid generator, thereby modifying the surface of the polymer film without damage to the polymer film. Also, an organic electronic device including the surface-modified polymer film can be improved in electrical characteristics and stability.

Abstract: Disclosed herein is a laminate comprising: a substrate; an organic surface modifying layer disposed on the substrate; and a porous organic semiconductor layer disposed on the surface modifying layer. Onto the substrate, introduction of the organic surface modifying layer having a low surface energy, and optionally the organic intermediate layer having a low glass transition temperature controls the self assembly of the organic semiconductor layer, allowing the porous organic semiconductor layer to have high crystallinity and large crystal grains. Also, provided is a highly efficient chemical sensor comprising the laminate.

Abstract: Disclosed is a graphene laminate including a first graphene layer, containing an electron-donating functional group, and a second graphene layer, disposed on the first graphene layer and configured to include graphene, wherein the second graphene layer is n-doped with the first graphene layer. Thereby, graphene is doped with amino-group-modified graphene, thus preventing the transparency of graphene from decreasing, and the extent of doping of graphene can be adjusted, and the doping effect can last a long time even without any protective layer.
