摘　　要：The carbon black/ionic liquid gels were used as the sensing materials in the gas sensor and sensor array for organic vapor detection.Results suggested that this gas-sensing material showed a good linear response towards the concentration of dichloromethane,tetrahydrofuran,ethyl cyanide,ethanol,acetone vapors with quite different sensitivity.These organic vapors were then successfully distinguished by the sensor array based on the carbon black/BmimPF6、EmimETSO4、EmimCF3SO3 gels and the principal element data analysis methods.The carbon black/ionic liquid gels were used as the sensing materials in the gas sensor and sensor array for organic vapor detection.Results suggested that this gas-sensing material showed a good linear response towards the concentration of dichloromethane,tetrahydrofuran,ethyl cyanide,ethanol,acetone vapors with quite different sensitivity.These organic vapors were then successfully distinguished by the sensor array based on the carbon black/BmimPF6、EmimETSO4、EmimCF3SO3 gels and the principal element data analysis methods.
