Abstract A kind of carbon nanotubes (CNTs) gas sensor modified by concentrated sulphuric acid and nitrating acid mixtures was developed based on printed circuit board, which was applied to detect sulfur hexafluoride (SF6) partial discharge (PD) decomposition components. Analyzed the conduction and of CNT films, and according to the temperature property test of sensor in vacuum, the relationship between resistance of two sensors and temperature was analyzed. Experiments were conducted for CNTs gas sensor in the laboratory using SF6 gas decomposition component testing device. Test results show that the modified CNTs sensor have good absorbability for SF6 decomposition components. Moreover, The influence of temperature is studied, and the result proves that the sensor showsd the best adsorption at temperature of 85℃.
