Due to their special characteristics of electrics, optics and mechanics, the composites of polymers and carbon nanotubes become the focus of research recently, and show their exciting application potential. The article introduces the electric mechanism of the composites. Two kinds of chemical sensors based on the composites of gel polymers and single wall carbon nanotubes were first fabricated and applied on an electronic tongue system developed in our lab. The responses of sensors in the different liquids were measured using impedance method, and the data were processed by using principle of component analysis (PCA) algorithm. The preliminary results of experiments show the sensors can better discriminate different tastes of acid, sweet, bitter and salty etc.
