Resin matrix composites(RMCs)with high dielectric constant(high-k)have attracted wide attentions of researchers worldwide owing to their excellent dielectric properties

outstanding processing feature and high mechanical properties as well as great potential in applications. High-k RMCs have been one hot issue in the field of functional materials in recent years. Higher dielectric constant

lower dielectric loss and excellent mechanical properties are the keywords for developing high-k RMCs. According to the recent progress in High-k RMCs

this paper reviews our researches emphatically on this issue.
