| 摘 要： | 利用最小二乘法，对辐照改性后P(VDF-TrFE)薄膜试样的介电常数谱进行v-F关系模拟，得出该材料具有与自旋玻璃体系及弛豫铁电体类似的性质．同时研究了其冻结温度随加工和辐照条件变化的规律．研究结果表明，通过适当选择加工和辐照条件，可以满足不同应用对铁电共聚物的要求．

| Abstract: | The least-square fitting results show that dielectric properties of electron irradiated P(VDF-TrFE) film follow the law originally obtained in spin glass system. Relation between temperature and processing and irradiation condition are also studied. It is possible to meet application requirement for ferroelectric polymers by suitable combination of processing and irradiation condition. |
