Polymer-Based Composites with High Dielectric Constant and Low Dielectric Loss

Due to the wide important application of the polymer-based composites with both high dielectric constant and low dielectric loss in such fields as electrical and electronic engineering, this paper reviews almost all the state-of-the-art research work focusing on them. In the attempt to establish the principles to design and prepare the polymer-based composites with high dielectric constant and low dielectric loss, the effects of functional fillers, polymer matrixes, and their interaction on the dielectric properties of the polymer-based composites are discussed in details. As a consequence, the future research trends are pointed out involving the development of the innovative approaches to prepare functional fillers with controlled structures, morphologies and sizes, advanced facile composite processes and techniques to adjust the interfaces, and the theoretical models to correlate dielectric properties with the structure of the functional fillers, etc.
