ppb High Performance Gas Sensor Capable of Sensing Nitric Oxide at Parts-Per-Billion Level and Fabrication Method by Solution Process

摘要

In the present exemplary embodiments, a carbon-based material, a conductive layer, is functionalized with a polymer having a plurality of amine groups, and the reactivity to a nitrogen-based gas is controlled by the concentration of a polymer having a plurality of amine groups according to a solvent, so that a nitrogen-based gas at ppb level It provides a gas sensor capable of selectively detecting and improving sensor responsiveness to close to 50%, and a method for manufacturing the same.
