(a) Real permittivity and (b) dielectric loss of PPO/BT composites with volume percent of BT as a function of frequency. The horizontal lines in (a) show the calculated values by the logarithmic rule of mixture.
Comparison of (a) real permittivity and (b) dielectric loss of composites with preparation methods as a function of BT content at 1 GHz.
Images of (a) HRTEM of encap-BT, (b) FESEM of the microtomed PPO/TAIC blend, FESEM of the fracture surface of (c) PPO/BT, and (d) PPO/TAIC/BT composites. The BT content of both composites in (c) and (d) is 40 vol %.
Comparison of real permittivity and dielectric loss of PPO/BT, LMW PPO/BT and LMW PPO/TAIC/BT composites at 1 GHz.
