Effect of Amphiphilic Coupling Agent on Dielectric Properties of MgNb2O6/Polystyrene Composites |
| 초록 |
Effects of amphiphilic coupling agent (trimethyloctylammonium bromide (TMOB)) on the microwave dielectric properties of MgNb2O6/polystyrene (PS) composites were investigated as function of MgNb2O6 content. With increasing of MgNb2O6 content, the dielectric constant (K) and dielectric loss (tanδ) of the composites increased, while the temperature coefficient of resonant frequency (TCF) decreased due to the dielectric properties of the individual components. The K of the composites filled with MgNb2O6 treated by TMOB was higher than that of the composites filled with pure MgNb2O6 at a given MgNb2O6 content. This result could be attributed to the increase in interfacial adhesion. Effects of preparation process on dielectric properties of the composites also discussed. |
