外文摘要：Carbon nanoparticles(CNPs)have received considerable attention due to their exceptional qualities and adaptability.Their unique physical and chemical characteristics make them extremely intriguing as materials for numerous high-potential applications,such as electronics and gas sensing.This study focused on producing carbon-based nanomaterial devices by deposition of flame-formed carbon nano-particles on a suitable substrate and investigating their gas-sensing properties.CNPs were produced in a fuel-rich laminar premixed ethylene/air flame and the collected CNP film was morphologically and electrically characterized.The electrical conductivity of the film was investigated as a function of ethanol concentration and amount of deposited material.Notably,CNP films exhibited high sensitivity to ambient ethanol gas concentrations,and rapid recovery times at room temperature,and showed a sensitivity increasing with the amount of deposited material and the surface complexity.Our findings demonstrate the high potential of combustion-generated CNPs as building materials for low-cost and portable ethanol sensors.
