ORGANIC FIELD EFFECT TRANSISTOR DEVICE COMPRISING HYBRID CHANNEL LAYER CAPABLE OF DETECTING ACTIVE OXYGEN SPECIES AND ACTIVE OXYGEN SPECIES DETECTION SENSOR COMPRISING THE SAME

摘要

The present invention is a substrate; a gate electrode formed on the substrate; an insulating layer formed on the gate electrode; a source electrode formed on the insulating layer; a drain electrode formed on the insulating layer to be spaced apart from the source electrode; and a hybrid channel layer formed on the insulating layer and positioned between the source electrode and the drain electrode, wherein the hybrid channel layer includes a p-type conductive polymer, a phenolic compound, and a halloysite nanoclay. It relates to an active oxygen species detection sensor including an organic field effect transistor device, characterized in that part or all of the hydroxyl groups included in the phenolic compound are exposed to the outside. According to the present invention, it is possible to provide an organic field effect transistor device including a hybrid channel layer having excellent mass productivity because the production process is simple and mass production is possible at low cost without additional equipment. In addition, the reactive oxygen species detection sensor of the present invention including the organic field effect transistor device has an effect that can repeatedly and continuously measure even a low concentration of active oxygen species.
