摘要：
The Ca0.7La0.2TiO3 ceramic with excellent dielectric properties was filled into cyanate ester (CE) resin to prepare Ca0.7La0.2TiO3/CE composite by a melt pouring technique. The results show that dense microstructure is observed in the composites with different filler volume fractions. The Ca0.7La0.2TiO3/CE composite with a high dielectric constant (ε) and low dielectric loss (tanδ) (ε=25.7, tanδ=0.0055, at 10 GHz) is obtained when the filler volume fraction reaches 40%. Meanwhile, the bending strength reaches 130 MPa. And the thermal conductivity increases to 0.8601 W/(m·K), which can effectively dissipate heat. TGA results show that compared with CE resin, the composites have higher thermal stability and have good application prospects in high-frequency communications, integrated circuits and other fields. © 2021, Editorial Office of Acta Materiae Compositae Sinica.
