Abstract
high-sensitivity volatile organic gas sensor was fabricated with nano scale carbon black as the active material. Due to the polarity of gas molecules and the influence of surface energy, carbon black will produce different intermolecular distances after adsorbing different gases, resulted in different electron transfer ability. In addition, the conductivity of carbon black will also be changed in different oxidizing and reducing gases, coupled with the conductivity of gas molecules themselves, resulting in different electrical response of the sensor under various volatile organic gases with various concentrations.
