摘要

设计并制造了一种温度控制在30-220℃范围内的电容电池和烘箱。几个侧链聚合物液晶的介电特性已经在17个频率范围内进行了测量，频率范围从10赫兹到10万赫兹，使用的是由作者之一(CGA1)建造的全自动微处理器控制桥。介电特性将与这些材料的DSC研究进行比较

Dielectric relaxation behavior of polymer liquid crystals at temperatures up to 220°C

A capacitance cell and oven capable of temperature control in the range of 30–220°C has been designed and constructed. The dielectric properties of several side-chain polymer liquid crystals have been measured at 17 frequencies ranging from 10 Hz to 100,000 Hz using a fully automated, microprocessor controlled bridge built by one of the authors (CGA1. The dielectric features will be compared with DSC studies of these materials
