Different Kinds of Carbon-Based Material for Resistive Gas Sensing

摘要

Gas sensing properties of networks made of carbon black, carbon nanofibers and carbon multi-walled carbon nanotubes are tested. The networks' reaction to vapors of volatile organic compounds is measured through their change of electrical resistance. The measured resistance increase is up to 27.7 % for carbon black, 40% for carbon nanofibers and 47.7% for multi-walled carbon nanotubes.
