Abstract: Aiming at the current research progress of dielectric elastomer materials， using the information visualization technology, the related literature in recent ten years was studied. The SCI core database of Web of Science was searched with the word "dielectric elastomer" as the key word. Using CiteSpace information visualization software, the data were analyzed. A number of co citation maps on dielectric elastomer were plotted. The research progress was reviewed, and the frontiers and hotspots were summarized. The results indicate that the field of dielectric elastomer material is under the period of great development and more scientific research are invested in this field in both China and the United States. After the search of the SCI core database of Web of Science, three key nodes with significant influence were obtained, which can reveal that the study of dielectric elastomer materials has great significance in the aspects of compositions, performances and methodology.

Key words: dielectric elastomer; frontiers; evolution; information visualization; CiteSpace
