Provided are a conductive ink, organic semiconductor transistor using the conductive ink, and method of fabricating the transistor. The conductive ink is used to form electrodes on an organic semiconductor while minimizing the damage of the organic semiconductor. The conductive ink is formed by mixing metal nanoparticles with a conductive polymer and used as an electrode material during the fabrication of the organic semiconductor transistor using a direct printing process. By using the conductive ink as the electrode material, the production cost of the organic semiconductor transistor can be greatly reduced.

Provided is a method of forming a fine pattern of a polymer thin film using a phenomenon that another material having a large difference in surface energy in comparison with a polymer thin film pattern is dewetted on the polymer thin film pattern. Two polymer materials having a large difference in surface energy can be applied to readily and conveniently form a fine pattern of a polymer thin film of micrometer or sub-micrometer grade.

An organic thin film transistor (OTFT), a method of manufacturing the same, and a biosensor using the OTFT are provided. The OTFT includes a gate electrode, a gate insulating layer, source and drain electrodes, and an organic semiconductor layer disposed on a substrate and further includes an interface layer formed between the gate insulating layer and the organic semiconductor layer by a sol-gel process. The gate insulating layer is formed of an organic polymer, and the interface layer is formed of an inorganic material. The OTFT employs the interface layer interposed between the gate insulating layer and the organic semiconductor layer so that the gate insulating layer can be protected from the exterior and adhesion of the gate insulating layer with the organic semiconductor layer can be improved, thereby increasing driving stability. Also, since the OTFT can use a plastic substrate, the manufacture of the OTFT is inexpensive so that the OTFT can be used as a disposable biosensor.

The detector includes a base portion; first and second electrodes disposed on the base portion and spaced apart from each other; a reactant layer disposed between the first and second electrodes on the base portion to react with a specific functional group contained in a fluid; and a protection medium layer surrounding the first and second electrodes and forming a reaction space to expose a portion of the reactant layer. In the detector, electrodes can be effectively protected at low cost, and a path for guiding a fluid to be detected can be provided.

Provided is a method of manufacturing an organic thin film transistor (OTFT). The method comprises forming all components in the OTFT including electrodes, an insulating layer, and an organic layer using laser printing. The laser printing allows formation of a fine pattern by selectively scattering toner only on a portion of a substrate irradiated by a laser beam while eliminating the need for a separate drying process by fixing the toner to the substrate using a fixing roller.

摘要:
Disclosed therein is an air conditioner for a vehicle, which includes an evaporator and a storage tank getting in surface contact with each other, thereby doubling a cold storage effect by directly transferring cold air of the evaporator to the storage tank in a cooling mode, maximizing the cold storage effect because condensate water generated from the surface of the evaporator additionally cools the surface of the storage tank, and effectively enhancing heat-exchanging performance without increasing capacity of the storage tank. The air conditioner further includes heat-exchanging means mounted inside the storage tank so as to enhance the heat exchange performance of a heat carrier more.
