Abstract:
Provided is a fiber web for a gas sensor. In one exemplary embodiment of the present invention, there is provided a fiber web for a gas sensor including nanofibers including a fiber-forming material and a sensing material for reacting with a target substance in a test gas. According to the exemplary embodiment, the fiber web for a gas sensor is capable of identifying the presence or absence of a target substance in a test gas and quantitatively determining the concentration of a target substance, and exhibits improved sensitivity due to having an increased area of contact and reaction with a target substance contained in a test gas. In addition, the fiber web for a gas sensor facilitates the detection of a target substance in a test gas at a low cost and thus can be widely used for the detection of various volatile organic compounds (VOCs) in households, the diagnosis of asthma or esophagitis or the identification of a patient suffering from the same, and the detection of hazardous materials in other fields of industrial safety.
