Polydiaminonaphthalene（PDAN）,as a conductive polymer,will become a novel functional material owing to its unique properties and potential applications.The electrochemical properties and structure of poly（1,5-diaminonaphthalene）（P1,5-DAN）prepared by electrochemical process are summarized.Combination of P 1,5-DAN with other functional materials can offer new materials with many interesting properties,for example,electrocatalysts,absorbents,chemical and biological sensors,and so on.Among them,poly 1,5-diaminonaphthalene has received increasing interest due to its affinity to some metal ions of the electron donating groups（amine and secondary amino groups）on the polymer chain in electrochemical experiments.The excellent adhesive property and dense structure of its film obtained by electrochemical synthesis are of great advantage to the modification of electrodes.Poly（1,5-diaminonaphthalene）can sensitively respond to specific chemical or biological species.The development of the electrodes modified by poly（1,5-diaminonaphthalene）film is prospected.
