Abstract
Disclosed are polymer nanofiber sensors for detecting gas, which generates visible color change although a specific gas having a concentration of less than 1 ppm is exposed to the sensor in a short time, in which it is impossible to detect the gas using existing colorimetric sensors, through securing high surface area and porosity, and a method of the same.
