Abstract: Modification of conductive polymer by doping nano-particles is an effective way to improve its performance. This paper introduced the preparation methods of polypyrrole nanocomposites at present which include electrochemical polymerization,chemical oxidation,template method,sol-gel method while the electrospinning method is commonly used to prepare nanofibers. According to its excellent conductivity and chemical properties,the applications of polypyrrole nanocomposites in sensors,biomedicine,electronic devices,cotton fabrics,adsorption,impurity removal,and corrosion protection are described. In addition,improving the accuracy of characterization of composite material and the dispersibility during blending are demanded to clarify the mechanism of liquid phase transformation into solid phase. At the same time,the key to improve the performance of nanocomposites is to control the relevant parameters of the interface and to improve their testing methods. The establishment of related models and the integration of microcosmic and macroscopic aspects are also important directions for future research.
