 Abstract: The author has being engaged in dielectrics in the past fifty years. The development and present study in insulated dielectrics were discussed. The study features and puzzle in dielectrics field were proposed. Functional dielectrics and insulated dielectrics were compared and analyzed. Several study methods and features of theory in this field were introduced to reveal the structure and relationship between structure and property. Property demand in engineering application of functional dielectrics and insulated dielectrics was discussed. Studying the hierarchical levels of movements and structures of polymer in time and space is the great challenge to explore the relationship between structure and property of dielectric materials. It is forecasted that the nanotechnology will revolutionize the structure design and application of dielectrics.

 Key words:  insulated dielectrics; functional dielectrics; insulation
