Abstract: Conducting polymer nanomaterials not only have high conductivity, but also have special properties of nanomaterials. Therefore, these materials have application prospect in many fields. In this paper, the synthetic methods of conducting polymer nanomaterials including template method and templateless method are discussed. The template method could be divided into hard and soft template methods. The advantages and disadvantages of each method are analyzed through taking the preparation of polyaniline as examples mainly. The development prospect of such conductive polymer nanomaterials is also presented.
