Besides fillers, the polymer matrix

除了填料外，聚合物基体在介电复合材料中也起着决定性的作用。基体的玻璃化转变温度和热分解温度通常决定了复合材料的使用温度范围。39-41 常规聚合物通常具有较低的玻璃<br>化转变温度和较低的介电常数，这限制了介电复合材料的应用领域。因此，具有高偶极单元的热稳定工程塑料（如尿素、砜和硫脲6,42）是高k纳米复合材料的理想聚合物基体。

Besides fillers, the polymer matrix also plays a decisive role in the dielectric composites. The glass transition temperature and thermal decomposition temperature of the matrix usually determine the service temperature range of the composites.39−41 Conventional polymers generally have a low glasstransition temperature and low dielectric constant, which limits the application area of the dielectric composites. Therefore, thermostable engineering plastics with high dipole units (such as urea, sulfone, and thiourea6,42) are ideal polymer matrix for high-k nanocomposites.<br>
